旋喷加筋水泥土桩锚支护技术在深基坑工程中的应用
摘要:旋喷锚索是将大直径水泥土桩体与普通锚索相结合的一种新型工艺，主要用于软弱土层中的基坑支护。与普通锚索相比，其锚固体直径大，承载力高，基坑位移控制效果更加理想。结合某工程实例，介绍旋喷加筋水泥土桩锚支护技术，并通过基坑围护墙顶水平位移、土体深层水平位移等监测，分析基坑变形控制效果。结果表明，该支护形式安全、经济，能为工程应用提供借鉴。
Abstract:The jet grouting anchor, a new technology which combines large-diameter cement-soil pile with conventional anchor, is usually applied in the foundation pit support in soft soil. Compared with conventional anchor, it has advantages for large-diameter and high bearing capacity. Then the displacement of excavation can be controlled effectively. Connecting the application of jet grouting reinforced cement-soil pile-anchor during an engineering case, the paper introduces briefly this support technology and analyzes the control effect of pit deformation by monitoring wall top horizontal displacement and the soil deep horizontal displacement. The results show this support form is safe and economic. It could provide references and suggestions for similar projects.
