西南某全强风化玄武岩边坡失稳机制分析

Analysis of the instability mechanism of a strong weathering basalt slope in southwest China

某高速公路边坡属开挖边坡,边坡岩土体为全强风化玄武岩,岩体破碎,在边坡开挖过程中发生变形,根据野外地质测绘及室内试验,通过对全强风化岩体的物质组成、物理力学参数等的研究,分析滑坡的成因,为防治方案提供一定的基础资料。

The slope of the slope of a highway is excavated on the slope of the slope,the slope rock soil is a strong weathering basalt,the rock mass is broken and deformation during the excavation of the slope.This paper based on the field geological mapping and indoor experiment,a nalyzesthe causes of the landslide caused by the material composition an d physical mechanical parameters of the fully weathered rock mass,and provides some basic information for the prevention and control plan.
