摘要
对各类危岩发育的宏观影响因素做了详尽分析,在宏观机理层次指出,结构面及其组合关系、软硬相间的岩层组合、地形地貌、岩性等是危岩发育的内在条件,地下水、重力卸荷作用、风化作用等是危岩发育的外在环境条件,暴雨、地震及人类活动是危岩发育的激发条件。并结合工程实例,对万州区长江沿岸的太白岩危岩带的成因进行了探讨。结论指出,弄清危岩的环境条件对岩坡稳定分析具有重要意义。
In this paper, the various influencing factors of unstable rock development are analyzed in detail. From the macroscopic mechanism viewpoint, the internal conditions including the structural plane and its combined relations, alternate rock strata combination of soft and hard rocks, land form and land feature, the external conditions including groundwater, loading, and weathering, the explosive conditions including rainstorm, earthquake and human activities are pointed out. Based on an engineering example, the causes of formation of Taibaiyan unstable rocks along the Yangtze River in Wanzhou district are discussed. The results show that for analysis of the slope stability, understanding of the conditions of the unstable rock development is very important.
