摘要
依托济南城市轨道交通6号线某车辆段为例,采用标准贯入试验对工程现场的强夯及未强夯区域进行了试验点位锤击数采集,并基于砂土液化的计算判别方法,对比分析了各区域的砂土液化情况.通过工程实例验证了标准贯入试验对于黄河流域轨道交通行业的砂土地层液化现象提供判别方法的可行性,以期为轨道交通工程建设提供安全保障及参考依据.
Abstract
Taking a vehicle depot of Jinan Urban Rail Transit Line 6 as an example,the standard penetration test was used to collect the number of hammer blows at the test points of the dynamic compaction and non dynamic compaction areas on the engineering site.Based on the calculation and discrimination method of sand liquefaction,the sand liquefaction situation in each area was compared and analyzed.The feasibility of using the standard pen-etration test as a discrimination method for the liquefaction phenomenon of sandy soil layers in the Yellow River Basin rail transit industry has been verified through engineering examples,in order to provide safety guarantees and reference basis for rail transit engineering construction.
