复合土钉墙在黄土地层基坑支护中的应用

Application of Composite Soil-nail Wall in Foundation Pit Retaining in Loess Strata

摘要:

概述了黄土质基坑的破坏成因，并以某电厂翻车机室基坑的支护为例，概述了场地的工程地质概况以及选用的支护方式，根据土质基坑的破坏模型进行基坑的稳定性验算并调整设计参数，确定最终设计方案。同时介绍了支护方案,即复合土钉墙的施工技术应用，基坑的变形监测；总结了施工经验和体会。

Abstract:

The paper summarized the damage causes of loess foundation pit, and took the example of a retaining project to sum up the geological situation of construction and the retaining methods. Based on the foundation pit damage model, the stability computation was made and designing parameters were adjusted to determine the final scheme. The retaining scheme was introduced including the application of composite soil-nail technology and monitoring on the foundation pit deformation. The construction experience was also presented.
