| 摘 要： | 本文以工程实例为依托,在现场大量调查、测试、试验的基础上,对一种新型碎裂结构岩体—充填胶结碎裂岩体的工程地质特性和成因机制进行了分析。此类岩体表观碎裂,但是由于岩块之间被钙质充填、胶结,使得表观碎裂的岩体在原位状态没有受到大的扰动的情况下具有较高的力学性能,其可以用作坝基岩体,与普通的碎裂岩体有着本质上的差别。该类岩体一旦受到外界大的扰动,其力学性能迅速降低,在施工中应该特别注意。 |

| Abstract: | The filling-cemented cataclastic rock masses are introduced in this study as a new type of cataclastic rock masses.The filling and cementation by calcium carbonate between rock masses lead to the high mechanical strength of the cataclastic rock masses in situ under certain circumstance of external disturbance.Unlike the common cataclastic rock masses with low mechanical strength under certain circumstance of external disturbance,they may be designed as dam-foundation rock masses.Care should be taken to distinguish them in engineering construction. |
