摘要
文中以某道路拓改工程为例,重点研究基于水流冲刷的市政涵洞软地基承载性能与加固技术,详细分析了软地基承载力与基础埋深系数、固结程度、涵洞基础宽度的关系,从打桩、扩大涵洞基础、设置截水墙、流水面硬化、换填片石等方面总结了软地基的加固技术要点,以期为类似项目提供参考.
Abstract
Taking a certain road renovation project as an example,this article focuses on the bearing performance and reinforcement technology of municipal culvert soft foundation based on water flow erosion.The relationship between soft foundation bearing capacity and foundation depth coefficient,consolidation degree,and culvert foundation width is analyzed in detail.The key points of soft foundation reinforcement technology are summarized from aspects such as pile driving,expanding culvert foundation,setting cutoff walls,water flow surface hardening,and repla-cing and filling with rubble,in order to provide effective reference for similar projects.
