复合注浆在深厚大卵石地层止水中的应用
摘要:以深厚大卵石地层深基坑工程止水为例,针对透水性强的卵石层地质特征,阐述了基坑止水设计新思路及试验过程,通过对地下水监测结果分析和研究,证明了该工艺的合理性,所取得的经验对于类似工程具有一定的参考意义。
Abstract:In the study of anti-seepage in deep foundation pit of deep and thick pebble stratum, focusing on the geological characteristics of pebble stratum with high permeability, new idea and specific test process of anti-seepage in foundation pit are introduced. Through the analysis of groundwater monitoring results, it proves the rationality of this technology, and the experience obtained has certain reference significance for similar projects.
