Slope stabilization treatment of this region including polyathylen strip method and thin layer hydrograsser method, some small slopes even have not been treated. A few of the treated slopes fail during heavy rainfall. The post method of treatmenting these slopes obviously doesn't function properly. The purposes of this research is to suggest suitable methods for gravel slopes, and consider slope behavior and stability.

当初公路沿线砾石边坡於设计阶段时，采用了包括植生带铺植工法及薄层喷植工法二种护坡工法，另部份边坡高度较小之路段未予植生处理；由於此路段边坡易受雨水侵蚀而形成侵蚀沟，并使其细粒料流失，造成边坡植生效果不佳，所采用之护坡工法无法达到其预期之效果，本研究目的为建议适合之工法应用於现地砾石边坡上，并探讨边坡之整体行为与稳定性。

Shule River project area is located in northwest China\'s Gansu province,Hexi Corridor,which is the largest agricultural crop production base of Gansu province and typically arid and semi-arid areas. There are characteristics such as scarce rainfall,the temporal and spatial distribution inequality,strong evaporation,fragile ecological environment,the limited quantity of surface water. Agriculture,the people\'s living and ecological environment are significantly dependent on the groundwater. Based on the collection and processing of regional hydrological and geological data and the groundwater monitoring data,using the numerical simulation,geostatistics theory and multi-objective evolutionary algorithm,this paper studied the monitoring and evaluation of groundwater resources from the three aspects: groundwater numerical simulation and prediction,groundwater spatial variability and distribution and optimization modeling and sloving of groundwater monitoring network. The main work and research lies:(1) Using Yumen-Tashi basin,Anxi-Dunhuang basin and Huahai basin as study area,this paper used modflow model to simulate groundwater flow of three areas.
