摘要
安康枢纽范围内膨胀土路堑边坡工程,开挖后其部分出现开裂、滑坡等问题。分析了该地区膨胀土特殊的工程特性及边坡失稳的机理,认为特殊的工程特性和水的影响是边坡失稳的主要原因。根据边坡失稳的类型,提出合理的治理措施,保证了边坡的稳定。
The cutting slope in expansive soil in the range of Ankang Hub, when excavated, suffered with cracking, sliding and other problems. This paper, through analysis of the special engineering characteristics of the soil and the slope failure mechanism, considered that these characteristics and water impact were the main reason causing the slope instability; then according to the type of slope failure, proper countermeasures were proposed.
