摘要
Abstract
During the construction of highway in soft soil area,drawing water in deep pool will have influence on nearly existing highway.This paper uses finite element analysis method,considering no reinforcement and "high pressure jet grouting pile and bored pile" reinforcement measure,presenting how draw water in deep pool influences on the deformation of existing highway roadbed.Analysis results show that the roadbed settlement has a nonlinear increase with the growth of dewatering depth,and the growth rate decreases as the dewatering depth grows;Pumping in a deep pool incurs uneven settlement of nearby roadbed,the roadbed settlement near the side of poll is bigger;the reinforcement measures have good control effect on the horizontal displacement and settlement of the roadbed.关键词
