| 摘 要： | 高切坡是三峡库区新的地质灾害形式。通过对重庆库区万州区47个高切坡的调查和试验分析表明,万州高切坡主要表现为崩塌破坏、表层风化破坏、差异风化破坏、和土体滑塌破坏4种形式。影响破坏模式的因素主要是构成高切坡的组成物质及其性质、水文气象条件、高切坡的形态和治理时间等。针对不同的破坏类型提出相应的防治措施,以指导设计与施工。

| Abstract: | Highly Incised Slope(HIS) is a new type of geological hazard in the mountainous region of Three Gorges Reservoir.Investigation and experimental analyses are carried out at 47 HISs in Wanzhou area.The findings show that there are four failure modes in HIS.They are collapse,surface weathering,diversity of weathering,and soil sliding or collapse.Factors of influencing on failure modes in HIS are(1) the HIS materials,HIS characteristics,the hydrologic and weather condition,the HIS shape,and the engineering treatment time.According to the different failure modes in HISs,stabilization methods are recommended to be the guideline of design and construction. |
