| 摘 要： | 汶川地震诱发了大量的次生地质灾害,陇南寨子崖危岩体在地震过程中发生了较大规模的崩塌,震后局部崩塌不断,严重威胁着灾后重建安置点数百人的生命安全,因此准确判断该危岩体稳定性,并采取相应的处理措施尤为重要。在研究寨子崖危岩体所处地质环境及危岩失稳的诱发因素基础上,分析了该危岩体的分布规律及形态特征,并采用工程地质分析法和极限平衡法对该区几处主要危岩单体的稳定状况进行了定性与定量分析评价。经分析判断均处于不稳定状态,需进行工程治理。针对每个危岩单体的具体特征,提出了小规模清方+锚固+SNS主动防护等的联合治理方案。

| Abstract: | Wenchuan earthquake has induced a great number of secondary geological disasters.A large-scale collapse of rock masses took place at Zhaiziya in southern Gansu in the earthquake and collapses continued after the earthquake which seriously threaten the safety of hundreds of people in the settlement area of post-disaster reconstruction.So,it is very important to adequately understand stability of the dangerous rock masses and take effective emergency measures.Based on the study of geological background condit... |
