- 摘要:
- 在山区修筑高等级公路不可避免地进行深挖高填，会形成大量的高陡路基边坡或者路堤边坡。由于岩土体原有的地质环境平衡被打破，客观上为这些边坡的坍塌、滑动等地质灾害创造了地质条件。工程实践表明，在我国已修建的山区高等级公路中，几乎是“无路不坍、无路不垮”，特别是在雨季，公路的坍方、滑坡更为普遍。所以如何正确认识山区公路边坡的地质条件、结构特点、形成机制和正确评价边坡的稳定性，已成为我国山区高等级公路建设中的重大地质工程问题。以某高速公路的边坡为例，详细阐述了采用“地质与工程”充分结合方法，评价该边坡施工全过程的稳定性状况，并以此为基础，提出了有效的治理措施。监测结果表明，治理工程实施后，边坡的稳定性达到了高等级公路的设计要求。
- Abstract:
- Constructing first-class highway in mountainous area inevitably to carry on deep cuts and high fills-in, which can form massive high steep roadbeds side slope or the slope of embankment.Because the gneiss original geology environment balance is broken, objectively created geological condition for collapse and slide.The project practice indicated that the constructed highway in our country in mountainous area is nearly "does not have the road without collapse, not to have the road without break down", in the rainy season, the road soil slip, the landslide is specially more common.How therefore correctly knew the the geological condition mountainous area road side slope, the unique feature, forming mechanism and the correct appraisal of side slope stability, has become the geological project question in our country mountainous area first-class highway construction.Take a highway side slope as an example, the combination methed of "the gology and the project" is elaborated in detail, the entire process stability of this side slope is appraised, and based on this, the effective government measure is proposed.The result indicated, after the government project implementation, the side slope stability has met the first-class highway design requirements.
