| 摘 要： | 截水-加强型复合土钉墙支护技术以其经济、安全、变形小、施工便捷等突出优点在软土地区基坑支护中应用越来越广泛,由于淤泥质土的高含水量、高孔隙比、高压缩性和低承载力的特点,在软土地区进行基坑支护具有一定的风险性。本文以中山花园酒店基坑支护工程监测为例,就深基坑开挖施工过程中支护结构的沉降、水平位移等监测进行分析总结,并对施工中出现的局部隆起现象进行探讨,根据监测结果得出软土地区采用该支护技术是安全可靠、经济可行的结论。

| Abstract: | With the outstanding advantages of low cost,safety,small distortion and short-date construction,the shoring for foundation pit technology of strengthen cut-off composite soil nailing wall is applied more and more extensively.There is definite risk for foundation pit shoring in soft soil stratum because of its high water-contain,high porosity rate,high compressibility and low loaded force.We take example for Zhongshan Garden drinkery measure of shoring for foundation pit to summarize the sedimentation and le... |
