软岩深路堑边坡工程问题综述

国内高速公路网和铁路客运专线的新建,出现了一批软岩深路堑边坡工程,其中坡体的开挖、支护出现了前所未有的难题。通过对软岩深路堑边坡坡体变形力学特性研究、稳定性评价、支护方法等关键技术进行综述,提出了研究的重点、方法以及存在的问题,并探讨了软弱岩体和高边坡应力的处置办法,以期对软岩深路堑边坡工程问题的研究提供借鉴。

Problems of High Weak-rock Slope

Problems in excavation and support of high weak-rock slope were come up with the newly constructions of highway nets and passenger dedicated line including many high weak-rock slopes. Reviews of many key techniques about high weak-rock slopes engineering are done, such as the rock distortion mechanism, slope stability estimation and slope support methods. The emphases and means of research are proposed as well as unsolved problems. Besides, methods and theories are discussed to deal with the weakness of rock and complex stress condition of high slope. Results mentioned above can be used for references about problems of high weak-rock slope.
