山区高速公路崩塌落石勘察设计浅析

Analysis of Survey and Design against Collapse and Rockfall in Mountainous Expressways

崩塌、落石已成为高速公路建设、运营中常见不良地质之一,严重威胁过往车辆的安全,并可能造成交通中断。结合西南地区多条山区高速公路勘察、设计、施工情况,就崩塌、落石勘察设计方法、原则进行探讨。

Collapse and rockfall have become of expressways, severely threatening the one of common unfavorable geology in construction and operasecurity of vehicles and possibly causing interruption of traffic. This paper probes into the survey and design methods and principles against collapse and rockfall in combination with the survey, design and construction of several mountainous expressways in south-west region.
