在公路路基工程中,路堑(半路堑)边坡的稳定性问题,涉及的范围较广,影响的因素较多,如果处理不当,小者阻碍施工进展,影响交通运输;大者导至严重事故,造成人民生命和国家财产的巨大损失。因此,如何保持公路路基工程的坚固稳定,确保公路运输畅通无阻,是我们公路勘察、设计、施工、养护、运输等部门经常面临的重要问题。 本文仅就湘东南桂公路及资公路的实地调查情况,对花岗岩地区公路路堑(半路堑)边坡的稳定性,提出一点粗浅的看法,供研讨。
In highway subgrade engineering, the stability problems of cutting (half-graben) slopes involve in a wide range and have many influencing factors. If handled improperly, the small ones will hinder the progress of construction and affect transportation; the big ones lead to serious accidents , Causing huge loss of people’s lives and state property. Therefore, how to maintain the stability of highway subgrade engineering and ensure the unobstructed transportation of roads is an important issue often faced by our departments in road survey, design, construction, maintenance and transportation. This article only on the southeast Hunan and Guangxi highway and capital highway field survey, the granite highway cutting (half-graben) slope stability, put forward a little superficial view for discussion.
