摘要
巫山县新城址的地质问题是当前工程地质界关注和争议的焦点，也是库区具有普遍性的问题。王家屋场滑坡是一个具有独特性的滑坡，它的发育具有特殊的区域地质构造和地貌环境。文中详细阐述了滑坡本身的地貌和岩体结构特点，分析得出滑坡经历了先期滑动和后期改造的复杂过程，先期滑动具有多次滑动性，后期改造作用不亚于先期滑坡作用，岩溶溶蚀作用自始至终是滑坡的主导作用，构造破碎为溶蚀作用提供了条件。目前滑坡在整体上是稳定的，但后期改造过程仍在继续，移民工程也严重影响着滑坡的稳定性，尤其应防止水向滑体渗漏。
The resettlement project is the key part of the Three Gorges Project on the Yangtze River.The geology of the new Wushan County site is the focus of current public concern a problem common in the Three gorges Reservoir region.The geomorphology and structure of the slide mass is analysed in detail.The results reveal that the landslide has gone through two stages of development;in the earlier stage there having been repeated small slides,while in the later stage,restructuring of the slidemass becoming dominant.Karstification was well developed especially where the rocks were structurally fragmented,leading to undermining the mass from depth.Although the slidemass now remains relatively stable,precautions should be taken to prevent the mass from saturation.
