强夯置换法在沿海填土地基加固中的应用

强夯置换法是一种经济而简便的地基加固方法,施工前应在现场选取典型的试验区域进行试验性现场施工,以确定其适用性及加固效果,指导大面积的工程施工。文章结合某工程地基加固的实例,通过对典型试验区的强夯置换试验,以及对静载荷试验、重型动力触探试验、标准贯入试验结果的分析,确定了强夯置换法加固填土地基的施工参数,验证了强夯置换法用于该填土地基的合理性。

Application of Heavy Tamping - Replacement Method in Strengthening Soil Filling Foundation

Heavy tamping-replacement method is a kind of economical and simple method to strengthen foundation. Prior to actual engineering project construction, a trial construction using this method should be carried out at a typical zone of the construction site to ascertain its applicability and strengthening effect, so as to instruct the large area engineering construction. Combined with a practical example of strengthening foundation, this paper introduces the heavy tamping-replacement test at a typical trial zone and analyses the test results from the static loading test, heavy dynamic cone penetration test and standard penetration test, which determine the related construction parameters for strengthening soil filling foundation and verify the rationality of this method.
