岩溶路基病害与处置技术国内外研究现状

随着我国西部大开发战略的实施,岩溶问题已成为南方岩溶地区突飞猛进的公路建设,特别是高速公路建设面临的主要地质问题。本文以近年来国内外与岩溶有关的公开出版的最新研究成果为基础,针对目前与岩溶路基病害处置密切相关的隐伏岩溶的探测技术、岩溶洞穴稳定性与风险评估、岩溶塌陷的试验测试、岩溶塌陷监测预报以及岩溶病害的防治方法等方面,系统总结了国内外学者的最新研究现状。最后,在分析国内外差距的基础上,提出我国岩溶路基病害防治技术的研究应包括岩溶路基病害的分类和处置方法体系研究、路基病害发育过程的大型模型试验研究、隐伏岩溶地球物理探测方法的有效性研究、高新技术在高风险区岩溶路基变形破坏监测中的应用研究等方面。 

STATUS QUO OF THE STUDY ON SUBGRADE DISEASES AND THE TREATMENT TECHNIQUES IN KARST AREA

Covering 3.63 million km~2of soluble rocks, China is one of the countries with most extensive distribution of karst. With the development of national economics, karst features have become a serious problem to the traffic constructions such as highway and railway. During the last decades, scientists and engineers have got great progresses in the treatment of karst features in construction. In this paper, based on the new publication, the authors try to summarize the new achievements in karst investigation, stabilities and risk assessment of caves, experiment and prediction of karst collapse, and the treatment of karst features in highway construction.
