Under compressive loading, the soft soil will be greatly deformed. Inflatable anchor makes a full use of this feature of soft soil. This paper discusses the characteristics of inflatable anchor and reviews the present state of development of inflatable anchor, the mechanism of load transferring and the anchoring mechanism. It is shown that the limit tensile load of inflatable anchor is related to many factors, including soil density, soft soil liquidity index, anchor length, inflatable air pressure, rubber thickness, rubber fiction, air inflatable volume and the anchoring depth. Among those factors, the anchor length is the most important. The limit tensile load of inflatable anchor is 4 times of that of helical plate anchor. The limit tensile load in the drainage test is 3~4 times of that in undrainage test. If the air pressure is constant, the limit tensile load varies greatly in different soils. The short anchor (about 100mm in length) will be loaded along the whole shaft. The long anchor (about 300mm in length) will be loaded only in the inflatable part., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=null,

columnId=1242116809164390686, journalTitle=科技导报, columnName=综述文章, runingTitle=null, highlight=null, articleAbstract=充气锚杆是一种全新概念的新型锚杆，它是充分利用软土在压力作用下可产生挤压变形的特性研发而成的。本文论述了充气锚杆的独有特点，对充气锚杆的研究现状、锚杆荷载传递机制，以及岩土锚固机制进行了论述。总结了充气锚杆的一些规律：① 充气锚杆的抗拔承载力主要与砂的密实度、软土的液限指数、锚杆长度、充气压力大小、橡胶膜的厚度、橡胶膜外表的粗糙度、充气扩大头体积、锚杆埋设深度等因素有关，其中，锚杆长度是最主要的影响因素；② 充气锚杆的极限抗拔承载力是螺旋锚杆的４倍，在软土的排水与不排水对比试验中，充气锚杆极限抗拔承载力相差3~4倍；③ 在充气压力一定时，不同土体，锚杆的抗拔承载力差别很大，短锚杆100mm时几乎全长受力，长锚杆200~300mm时只在锚杆充气段上部分受力。, authors=^{彭文祥，曹佳文}, authorsList=彭文祥;曹佳文, authorCompany=中南大学地学与环境工程学院，长沙 410083, correspAuthors=null, authorNote=null,
