| 摘 要： | 本文分析了巴东新城区巴东组第3段岩体中软弱夹层的分布特征、滑坡滑带的发育特征,结果表明巴东组第3段岩体中发育的滑坡滑带可与原岩中的软弱夹层对应,软弱夹层受构造剪切和地下水泥化作用发育成以碎石夹泥或黏土夹碎石为主的滑带。分析认为黄土坡滑坡、赵树岭滑坡的深层变形与巴东组第3段次级褶皱发育、层间劈理密集导致岩体破碎有关,而两滑坡滑体结构差异主要原因是原岩中夹层发育密度差异所致。

| Abstract: | The distribution characteristics of weak intercalations and the development characteristics of landslides sliding zone in rock mass of the third Member of Badong Formation in new county-site town of Badong are studied in this paper. The results show that the sliding zone of landslides which developed in the third Member of Badong Formation corresponded to the sedimentary interlayers in the original rock. The intercalated dislocation caused by tectonic process in the interlayers evolved to landslides sliding zone by groundwater sliming effect. This effect is shown as the gravels with intercalated mud or the clay with intercalated gravels. The analysis shows that the deep-seated deformation in Huangtupo landslide and Zhaoshuling landslide were related to the broken rocks caused by the secondary fold and interbeded cleavage. The difference between the two landslide structure lied in the interlayer density in the original rock mass. |
