膨胀性软岩是近年来我国铁路、公路建设中经常遇到的特殊土,由于其具有强度低、遇水膨胀、崩解、软化,失水干缩、流变特征明显等不良工程特性,在这类岩层中修筑的边坡经常发生崩塌、滑坡等不良工程地质问题。本文在软岩边坡破坏特点、软岩流变特性调查研究的基础上,揭示了软岩边坡变形、破坏机制,提出了适宜于膨胀性软岩的边坡加固对策。
Expansive soft rock is a kind of special soil often encountered in the construction of railway and highway in our country in recent years. Due to its poor engineering characteristics, such as low strength, water swelling, disintegration, softening, water loss and shrinkage, and obvious rheological characteristics, The slopes built in this type of rock often collapse, landslide and other bad engineering geological problems. Based on the investigation of the failure characteristics of soft rock slope and the rheological properties of soft rock, the deformation and failure mechanism of soft rock slope are revealed, and the countermeasures of slope reinforcement suitable for expansive soft rock are proposed.
