摘要
扁铲侧胀试验是一种新型的原位测试技术,文章在分析扁铲侧胀试验原理的基础上,对比分析了国内外利用扁铲侧胀试验水平应力指数KD求解静止侧压力系数K0的各种经验公式,通过对无锡地铁1、2、3号线及部分深基坑工程的扁铲侧胀试验资料的整理和分析,将国内外的经验与无锡本地土性结合,最终提出了适用于无锡地区的经验公式。
DMT was a kind of new in situ test techniques. Based on the principle of the test and data at home and abroad, experience formulae of lateral earth pressure coefficient at rest were obtained by stress level.Meanwhile, combined with Wuxi metro line 1,line 2, line 3 and other deep excavations, the DMT data were summarized and analyzed, and the experience formula were established, which could apply to soil layers in Wuxi.
