In recent years, pumped storage power stations have developed rapidly, and their construction often faces the problem of mixed utilization of soft and hard rock. Soft rock has poor lithological properties, exhibiting significant breakage during construction. Whether mixtures of soft and hard rock can meet the requirements for dam strength and permeability characteristics requires further investigation. Field rolling compaction tests were conducted on soft and hard rockfill materials for a proposed pumped storage power station in Anhui Province, China, to investigate their physical, mechanical, and permeability characteristics under different compaction parameters. A comprehensive test scheme was designed to compare the compaction outcomes under combined conditions of roller weights (22 t and 26 t), water contents (5% and 10%), lift thicknesses (0.6 m and 0.8 m), and number of rolling passes (6, 8, and 10). A novel tensile direct shear test method was employed to measure the in-situ shear strength indices of the compacted rockfill and to identify the compaction parameters meeting the design requirements. This approach bridged the gap between laboratory tests and field conditions, offering a direct basis for reevaluating dam slope stability. The results showed that under identical compaction parameters, the dry density, permeability coefficient, and shear strength of the mixture containing 50% carbonaceous sericite phyllite were slightly lower than those of the sericite phyllite mixture. The dry density of the mixtures increased with the number of compaction passes, showing a convergent trend. Increasing the roller weight and reducing the lift thickness significantly improved the compaction quality. Regarding particle breakage characteristics, breakage occurred mainly in the surface layer of the lift during compaction, while the rockfill at deeper locations experienced minimal breakage due to the encapsulating effect of finer particles. The sericite phyllite mixture primarily experienced breakage of large particles, whereas the carbonaceous sericite phyllite mixture underwent repeated breakage in the surface layer during compaction, resulting in a powdery texture after compaction. Under a lift thickness of 80 cm, the strength parameters obtained using a 22 t vibratory roller with 10 compaction passes were essentially identical to those obtained using a 26 t vibratory roller with 8 passes. Based on the test results and considering both on-site construction quality and efficiency, it is recommended that for the sericite phyllite mixture, the construction parameters should be a lift thickness of 80 cm, a water content of 10%, and compaction with either a 22 t vibratory roller for 10 passes or a 26 t vibratory roller for 8 passes per lift.

近年来,抽水蓄能电站快速发展,建设过程中经常面临软硬岩混合利用的问题。软岩岩性较差,在施工过程中存在明显破碎现象,软硬岩混合料是否能满足筑坝强度和渗透特性的要求值得进一步探究。对安徽某拟建抽水蓄能电站的软硬岩筑坝料开展现场碾压试验,研究其在不同碾压参数条件下的物理力学和渗透特性。设计了全面的试验方案,比较了不同碾重(22、26 t)、加水量(5%、10%)、铺层厚度(0.6、0.8 m)和碾压遍数(6、8、10遍)组合条件下的碾压效果。采用新型张拉式直剪试验方法现场测定碾压后堆石料的抗剪强度指标,给出了满足设计要求的碾压参数,弥补了室内试验与现场工况的差异,为坝坡稳定性复核提供了直接依据。研究表明,相同碾压参数条件下,掺50%含碳质的绢云千枚岩混合料的干密度、渗透系数、抗剪强度均比绢云千枚岩混合料略小;混合料干密度随碾压遍数增加而增大,并呈现收敛趋势;提高碾重与减小铺层厚度均能显著提升压实质量。在颗粒破碎特性方面,碾压过程中颗粒破碎主要发生在铺层表层,而深层位置的堆石料由于细颗粒的包裹作用基本不发生破碎。绢云千枚岩混合料主要为大颗粒破碎,而含碳质绢云千枚岩混合料在碾压表层发生多次破碎,碾后呈粉质。在铺层厚度80 cm条件下,22 t振动碾碾压10遍得到的强度参数与26 t振动碾碾压8遍的强度参数基本相同。基于试验结果并综合考虑现场施工质量和效率,建议对绢云千枚岩混合料采用铺料层厚80 cm、加水量10%,各铺层采用22 t碾重振动碾压10遍,或采用26 t碾重振动碾压8遍的施工参数。

近年来,抽水蓄能电站快速发展,建设过程中经常面临软硬岩混合利用的问题。软岩岩性较差,在施工过程中存在明显破碎现象,软硬岩混合料是否能满足筑坝强度和渗透特性的要求值得进一步探究。对安徽某拟建抽水蓄能电站的软硬岩筑坝料开展现场碾压试验,研究其在不同碾压参数条件下的物理力学和渗透特性。设计了全面的试验方案,比较了不同碾重(22、26 t)、加水量(5%、10%)、铺层厚度(0.6、0.8 m)和碾压遍数(6、8、10遍)组合条件下的碾压效果。采用新型张拉式直剪试验方法现场测定碾压后堆石料的抗剪强度指标,给出了满足设计要求的碾压参数,弥补了室内试验与现场工况的差异,为坝坡稳定性复核提供了直接依据。研究表明,相同碾压参数条件下,掺50%含碳质的绢云千枚岩混合料的干密度、渗透系数、抗剪强度均比绢云千枚岩混合料略小;混合料干密度随碾压遍数增加而增大,并呈现收敛趋势;提高碾重与减小铺层厚度均能显著提升压实质量。在颗粒破碎特性方面,碾压过程中颗粒破碎主要发生在铺层表层,而深层位置的堆石料由于细颗粒的包裹作用基本不发生破碎。绢云千枚岩混合料主要为大颗粒破碎,而含碳质绢云千枚岩混合料在碾压表层发生多次破碎,碾后呈粉质。在铺层厚度80 cm条件下,22 t振动碾碾压10遍得到的强度参数与26 t振动碾碾压8遍的强度参数基本相同。基于试验结果并综合考虑现场施工质量和效率,建议对绢云千枚岩混合料采用铺料层厚80 cm、加水量10%,各铺层采用22 t碾重振动碾压10遍,或采用26 t碾重振动碾压8遍的施工参数。

In recent years, pumped storage power stations have developed rapidly, and their construction often faces the problem of mixed utilization of soft and hard rock. Soft rock has poor lithological properties, exhibiting significant breakage during construction. Whether mixtures of soft and hard rock can meet the requirements for dam strength and permeability characteristics requires further investigation. Field rolling compaction tests were conducted on soft and hard rockfill materials for a proposed pumped storage power station in Anhui Province, China, to investigate their physical, mechanical, and permeability characteristics under different compaction parameters. A comprehensive test scheme was designed to compare the compaction outcomes under combined conditions of roller weights (22 t and 26 t), water contents (5% and 10%), lift thicknesses (0.6 m and 0.8 m), and number of rolling passes (6, 8, and 10). A novel tensile direct shear test method was employed to measure the in-situ shear strength indices of the compacted rockfill and to identify the compaction parameters meeting the design requirements. This approach bridged the gap between laboratory tests and field conditions, offering a direct basis for reevaluating dam slope stability. The results showed that under identical compaction parameters, the dry density, permeability coefficient, and shear strength of the mixture containing 50% carbonaceous sericite phyllite were slightly lower than those of the sericite phyllite mixture. The dry density of the mixtures increased with the number of compaction passes, showing a convergent trend. Increasing the roller weight and reducing the lift thickness significantly improved the compaction quality. Regarding particle breakage characteristics, breakage occurred mainly in the surface layer of the lift during compaction, while the rockfill at deeper locations experienced minimal breakage due to the encapsulating effect of finer particles. The sericite phyllite mixture primarily experienced breakage of large particles, whereas the carbonaceous sericite phyllite mixture underwent repeated breakage in the surface layer during compaction, resulting in a powdery texture after compaction. Under a lift thickness of 80 cm, the strength parameters obtained using a 22 t vibratory roller with 10 compaction passes were essentially identical to those obtained using a 26 t vibratory roller with 8 passes. Based on the test results and considering both on-site construction quality and efficiency, it is recommended that for the sericite phyllite mixture, the construction parameters should be a lift thickness of 80 cm, a water content of 10%, and compaction with either a 22 t vibratory roller for 10 passes or a 26 t vibratory roller for 8 passes per lift.
