从清江流域瓦屋场滑坡复活看人类对坡体的利用

居住在山区的人们主要活动空间是斜坡。人们对斜坡利用的有效与否是由人们对斜坡认识充分与否决定的。倘若人们对斜坡认识不足，就可能遭受因斜坡失稳所带来的损失。因此，对这类斜坡的稳定状况的正确认识很有必要。以清江流域典型滑坡——瓦屋场滑坡的复活为例，通过介绍清江流域瓦屋场滑坡人类活动与该滑坡产生的变形情况，根据滑坡体工程地质条件，针对变形原因用萨尔玛法及不平衡推力法进行了稳定分析，同时对复活机制进行分析。在此基础上按照顺应性准则和协调性原则，提出相应的工程治理措施。鉴于该滑坡为该地区的典型滑坡，从灾害学角度说明人类在利用坡体前，对坡体稳定状况认识的重要性并给出人们合理利用该地区自然边坡的建议。

Viewing the uses of slopes from the analysis of the reviving of Wawuchang old landslide in the Qingjiang Valley

The slopes are the main territory for people residing in mountainous area. Whether the slopes in the area are utilized effectively depends on whether people recognize them clearly. If people do not recognize the slopes amply, they will suffer the loss made by the stability failure of the slopes. So, it is necessary to understand the stability of the slopes properly. We give a typical example of the reviving of Wawuchang old landslide in the Qingjiang Valley and explain the situation of the landslide deformation in this paper. Based on the engineering geological conditions, the engineering control measures to the old landslide are put forward after the stability analysis of the old landslide with the method of Sarma and unbalanced-thrust, and the analysis of reviving mechanism has been analyzed according to the conformity criteria and harmony principle. The suggestions as to how to make use of natural slopes in this area are made, and the importance of the stability situation of slopes before the utility of the slopes is illuminated on the point of view of the calamity in this paper.
