摘要/Abstract

摘要： 贵州属典型的山区，城市及周边存在较多高位危岩体，其失稳将带来极大的人生威胁和财产损失。通过贵阳市某高位危岩体的勘查及防治措施，总结探索出城市高位危岩体的形成因子，主要包括地形地貌、地质岩性、地质构造、风化卸荷、水、植物根劈、人类活动等，进行了详细分析阐述，并提出了相应的防治对策，有一定的实用参考价值。

Abstract: Guizhou is in a typical mountain terrain. There are many highrisk rock fall bodies in and surrounding the urban area of the city. With the increase quality of life, the instability induced by these highrisk rock falling bodies has drawn more and more attentions by the public and governmental agencies. This paper presents the investigation and remediation of rock fall hazards in Guiyang City. Factors, such as; topographical conditions, geological conditions od bedrock, tectonic structures, degree of weathering and unloading effect on the rock outcrops, role of surface and groundwater, vegetation and human activities; that might attribute to the rock falls have evaluated. The remediation measures are also proposed in the paper.

Key words: High-risk Falling Rock Body, Rock Fall Formation Factors, Prevention and Remediation
