风化岩路基填料沉降观测试验研究

摘要

为了揭示风化岩填料路基的工程性质,结合室内击实实验与施工段现场沉降观测实验,深入分析了风化岩路基沉降随时间的变化规律,同时,对风化岩填料路基的边坡防护进行了概述.该研究成果可用于指导、评价山区高速公路风化岩路基填筑,这不仅是对保护环境、实施可持续发展战略的双重要求,而且具有较高的经济和社会效益.%In order to reveal the weathered rock subgrade engineering properties of packing, combining with the compaction test and construction of indoor experiment site settlement observation period, in-depth analysis of the rock embankment settlement may chang with time and the weathered rock fill embankment slope protection is also taken into consideration.Therefore this research results can be used to guide mountainous highway roadbed compactness of a weathered rock,which not only benefits environmental protection and sustainable development strategy, but also meats the dual requirement with high economic and social benefits.
