Aiming at the calculation problem of soil pressure in foundation pit engineering, an analytical method for soil pressure was established, and the influence effects of various factors were analyzed. Based on the basic assumptions of Coulomb's soil pressure theory, and fully considering the friction angle between the wall back and backfill, the soil internal friction angle, foundation pit excavation depth and other factors, a soil pressure calculation model was constructed, and quantitative formulas for soil pressure and its influence range induced by excavation disturbance were proposed. Through the sensitivity analysis of influencing factors, the influence order of each factor on the excavation influence range was clarified under the conditions with or without steel supports. The variation laws of the influence range under different working conditions and excavation stages were studied, and comparative verification was carried out. The results show that the distribution patterns of soil pressure along the foundation pit excavation depth from the two methods are consistent, which verifies the accuracy of the model. Sensitivity analysis shows that the excavation depth of a foundation pit exerts the most significant effect on the excavation influence range without supports, and the excavation depth of the foundation pit remains the main controlling factor after steel supports are installed. The model proposed in this paper can quantitatively analyze the soil pressure distribution and disturbance influence range during the foundation pit excavation of a 110 kV substation as part of a supporting project of an energy development base in Hefei, Anhui Province. The results can provide a theoretical reference for the design and analysis of foundation pit engineering of related energy and mineral resources development infrastructure.

针对基坑工程土压力计算问题,建立了一种土压力解析方法,分析了各因素影响效应。基于库伦土压力理论的基本假设,综合考虑墙背和填土间的摩擦角、土体内摩擦角、基坑开挖深度等因素,构建了土压力计算模型,提出了开挖扰动引起土压力及其影响范围的量化公式。通过影响因素敏感性分析,明确了有无钢支撑条件下各因素对非开挖影响范围的影响顺序,研究了不同工况和开挖阶段下影响范围的变化规律,并进行对比验证。结果表明,两者在土压力沿基抗开挖深度分布形态上一致,验证了模型的准确性。敏感性分析表明,无支撑时基坑开挖深度对开挖影响范围的作用最显著,设置钢支撑后基坑开挖深度仍为主要控制因素。本文模型可较好地量化分析安徽合肥某能源开发基地配套项目110 kV变电站基坑开挖过程中土压力分布及扰动影响范围,后续可为相关能源及矿产资源开发基础设施基坑工程设计分析提供理论参考。

针对基坑工程土压力计算问题,建立了一种土压力解析方法,分析了各因素影响效应。基于库伦土压力理论的基本假设,综合考虑墙背和填土间的摩擦角、土体内摩擦角、基坑开挖深度等因素,构建了土压力计算模型,提出了开挖扰动引起土压力及其影响范围的量化公式。通过影响因素敏感性分析,明确了有无钢支撑条件下各因素对非开挖影响范围的影响顺序,研究了不同工况和开挖阶段下影响范围的变化规律,并进行对比验证。结果表明,两者在土压力沿基抗开挖深度分布形态上一致,验证了模型的准确性。敏感性分析表明,无支撑时基坑开挖深度对开挖影响范围的作用最显著,设置钢支撑后基坑开挖深度仍为主要控制因素。本文模型可较好地量化分析安徽合肥某能源开发基地配套项目110 kV变电站基坑开挖过程中土压力分布及扰动影响范围,后续可为相关能源及矿产资源开发基础设施基坑工程设计分析提供理论参考。

Aiming at the calculation problem of soil pressure in foundation pit engineering, an analytical method for soil pressure was established, and the influence effects of various factors were analyzed. Based on the basic assumptions of Coulomb's soil pressure theory, and fully considering the friction angle between the wall back and backfill, the soil internal friction angle, foundation pit excavation depth and other factors, a soil pressure calculation model was constructed, and quantitative formulas for soil pressure and its influence range induced by excavation disturbance were proposed. Through the sensitivity analysis of influencing factors, the influence order of each factor on the excavation influence range was clarified under the conditions with or without steel supports. The variation laws of the influence range under different working conditions and excavation stages were studied, and comparative verification was carried out. The results show that the distribution patterns of soil pressure along the foundation pit excavation depth from the two methods are consistent, which verifies the accuracy of the model. Sensitivity analysis shows that the excavation depth of a foundation pit exerts the most significant effect on the excavation influence range without supports, and the excavation depth of the foundation pit remains the main controlling factor after steel supports are installed. The model proposed in this paper can quantitatively analyze the soil pressure distribution and disturbance influence range during the foundation pit excavation of a 110 kV substation as part of a supporting project of an energy development base in Hefei, Anhui Province. The results can provide a theoretical reference for the design and analysis of foundation pit engineering of related energy and mineral resources development infrastructure.
