盾构法施工对地层扰动的试验研究

Test research on the behavior of the disturbed soiled by shield tunnelling

采用静力触探试验来研究盾构推进这种动态施工对地层扰动的影响 ,通过对土层力学参数的试验数据进行整理分析 ,总结了盾构法施工对周围地层扰动的一般影响规律 ,并初步定量地描述了这种变化情况。

This paper performs an experimental study on disturbed ground during tunneling through static cone penetration test. Based on the analysis of soil mechanics parameters collected from the test, general influence laws of disturbed ground in shield tunnel are obtained, and quantitative description of disturbed ground is also discussed.
