| 摘 要： | 对地铁喷射注浆法应用于某地铁工程围护结构止水帷幕先期试验的监测数据进行了深入分析。研究结果表明:直桩或斜桩在施工时对周围土体的深层水平位移的影响范围为距桩心3 d范围内,而在1 d范围内影响特别明显;MJS法能改善距桩心1.5 d范围内的土体强度,而在0.5 d~1.5 d范围内,桩体与土体之间将形成一强度由强到弱的过渡区;直桩施工时在距桩心1 d范围内的地表土体将隆起,而在1 d~2.5 d范围内将下沉。

| Abstract: | This paper makes deep analysis to the monitored data of the curtain for cutting off water experiment based on the Metro Jet System(MJS).The study indicates the following results: the influential range of deep horizontal displacements of soil deformation in piling of vertical and batter pile is 3d,while the influence is especially obvious in the range of 1d;the soil strength in range of 1.5d from the pile centre can be improved by the MJS,while in the range of 0.5d-1.5d,a special area where the strength is g... |
