8000 kN·m能级强夯处理填土地基有效加固深度试验

摘要

针对某工程高填方地基，采用8000 kN·m高能级强夯处理填土地基，通过静力触探试验、动力触探试验、探井、浅层平板载荷试验，评价8000 kN·m能级强夯处理填土地基的加固效果，得出强夯的有效加固深度为10.0 m，并根据强夯有效加固深度实测结果，提出基于梅拉公式计算结果的修正系数为0.353，其结果可为类似工程提供设计及施工参考。%This paper uses the high energy dynamic compaction with energy of 8 000 kN·m for a project of the high-filled foundation. The reinforcement effect of filled foundations strengthening with the high energy dynamic compaction method of energy 8 000 kN·m is evaluated through the static cone penetration test, dynamic cone penetration test, well excavation and plate loading test. The effective reinforcement depth of this dynamic compac-tion construction is improved. Based on the measured value of the effective reinforcement depth of dynamic com-paction, the correction coefficient 0.0353 is putted forward according to Menard formula. The research results will provide certain reference value for the similar projects.
