天津临港工业区地基土抗剪强度指标分析研究

On analysis of shearing strength indexes of Lingang industrial park in Tianjin

介绍了天津临港工业区的工程地质条件,对该区深基坑支护设计中最常采用的快剪和固结快剪强度指标参数进行了统计分析,并查明该工业区不同土层直剪试验指标区域分布规律和特点,以指导该区基坑支护设计工作,为其提供科学的抗剪强度指标依据,从而保证基坑工程的经济安全。

The paper introduces the engineering geological conditions for Lingang industrial park of Tianjin,analyzes the intensity index and parameter of fast shear and concretion shear,proves the distribution and features of the direct shear test index divisions at various stratum,so as to direct the design for the foundation pit support,provide scientific shearing intensity index,and ensure the money-saving and safety of the foundation pit projects.
