摘要
通过对深圳地铁暗挖施工的离心模型试验研究,得到了随时间变化的地表沉降槽变化规律曲线。表明在富水地层控制降水隧道开挖施工中,由于水平旋喷桩具有较好的地层加固和止水作用,可以有效地控制地表沉降。
With centrifugal model test study of covered excavation construction of Shenzhen Subway,anthors got the change rule curve of ground surface sedimentation slots which change along with variation of time.Results indicate that the horizontal rotation spray pile has good strata strengthening and water-stop effect and can effectively control ground surface sedimentation in excavation of control water level lowering tunnels in water rich strata.
