对不良地质地带公路路基失稳预控措施的分析

Analysis on Pre-control Measures for Highway Subgrade Failure in Unfavorable Geological Zone

在公路工雀施工过程中,经常碰到不良地质,对公路路基的稳走性造成了不利影响。因此必须采取合理的措施,处理公路路基施工中不良地质,以保证公路工程施工质量。针对本地区不良地质地带的公路路基出现的不均匀沉降和土坡的滑动失稳情况,对路基飾滑动失稳原因进行分析,提出路基坡体的滑动失稳的预控和防治措施。

In the process of highway engineering construction,bad geology is often encountered,which has adversely affected the stability of highway subgrade.Therefore,reasonable measures must be taken to deal with the bad geology in the construction of highway subgrade to ensure the quality of highway construction.In this paper,the uneven settlement of the roadbed in the unfavorable geological zone of this region and the sliding instability of the soil slope are analyzed.The reasons for the sliding instability of the subgrade are analyzed,and the pre-control and prevention measures of the sliding instability of the subgrade slope are proposed.
