考虑天然透水地层的公路路基地基优化处理技术
Optimization Techniques for Highway Subgrade Foundation Considering Natural Permeable Strata
摘要
Abstract
In the construction of highway embankments in the southeastern edge of the Qinghai-Tibet Plateau,there are widespread weak foundations due to poor drainage and excessive water accumulation.This article classifies the natural foundation structures along the Jiuma Expressway,divides them into permeable and impermeable layers,analyzes the types and causes of roadbed drainage diseases,and proposes a comprehensive foundation treatment and prevention method that considers the natural permeable layer structure for roadbed drainage.The aim is to provide scientific basis for the selection of internal water bodies and lower foundation treatment methods for the roadbed,and to provide guidance for future engineering construction in the northwest Sichuan region,and to provide reference for similar projects.关键词
