软基处理加固效果的试验研究及相关问题的处理

Experimental Study and Problem Disposal on Reinforcement Effect of Soft Base

根据采用堆载预压、真空排水预压、预应力管桩、CFG桩、联合桩不同处理方式对深厚软土的加固试验,基于对现场试验测试数据的整理分析和加固前后原位测试及土工试验数据的对比研究,对加固效果初步分析,提出在实施阶段中的建议及一些问题的处理方法。

According to reinforcement experiments with different treatment methods （including preloading, vacuum drainage preloading, prestressed concrete pipe pile, CFG pile and combined pile） to deep soft soil, and based on the comparison of finish analysis to test data on field, in situ test before and after the reinforcement and geotechnical test, an initial analysis has been made to the reinforcement effect, and some advices and problem dis- posal methods are brought forward.
