福建南平安丰自来水厂滑坡特征及治理对策

持续强降雨导致安丰水厂后山坡坡面变形开裂，形成了一个规模较大的滑坡，严重威胁水厂安全。采用钻探、物探（地质雷达和面波法）和地表工程地质测绘等综合手段，查明了滑坡发育机制，认为坡体土层松软，风化差异大，透水性强，坡面相对较陡是滑坡发生的内因，降雨是诱发滑坡最主要的外在因素。稳定性计算表明，该滑坡目前处于蠕滑极限平衡状态。应急排险及后期治理施工措施的成功，可为类似滑坡地质灾害的防治提供经验。

Anfeng Waterworks Landslide Features and Governing Countermeasures, Nanping, Fujian

The sustaining rainfall has caused slope deformation and disintegrating at the back hill Anfeng waterworks, a rather large scale landslide has been formed, and seriously threatening waterworks safety. Integrated means of drilling, geophysical prospecting （geological radar and surface wave method） and surface engineering geological mapping have found out the landslide development mechanism. Considered that the soft slope soil, differential weathering, strong permeability, rather steep slope are the internal causes, while the rainfall is the main external cause to induce landslide. The stability computation has demonstrated that the landslide is now in creeping critical equilibrium state. The successful emergent danger removal and later stage fathering operation measures can be the reference for similar landslide geological hazard control.
