Learned from the final report on direct and indirect participation in the whole process of construction management of the Luosiwan Hydropower Station, at present there are certain common problems in legal knowledge and contract reputation in cost control of hydropower construction in China.

), Diqing prefectural government and provincial investment corporation, the Luosiwan Hydropower Station is the construction project, in which the Diqing Zang Autonomous Prefecture made its largest investment since the founding of the People s Republic of China.

Treatment Measures Taken in Construction of Power Tunnel for Luosiwan Hydropower Station;

Design Features of Flushing Sluice and Flood Discharging Sluice Service Tainter Gates for Luosiwan Hydropower Station;

Test and Study of Surge in Surge Chamber for Luosiwan Hydropower Station;

Countermeasures for slope perils on the left bank in Manwan Hydropower Station;

Analysis of the spatial-temporal characteristics of R value in the storage areas of Manwan Hydropower Station may supply good advices to prevent soil erosion effectively in local region.

Stability analysis of high inlet slope for Xiaowan Hydropower Station;

In the Feasibility Report of Xiaowan Hydropower Station,construction schedule will be much slowed down due to more orifices in the dam body,reservoir filling will start 12 years later after the construction of reservoir has begun.

Prior to the joint grouting work of the Xiaowan hydropower station,we conduct indoor and On-site slurry performance tests which provide scheme and basis for the construction.

In this paper, coupling of stress and seepage fields at the damsite area of the Xiaowan hydropower project is analyzed, and the fractal effect of rock fractured surface on the seepage flow in fractured rock masses is studied by means of numeric simulation of single fracture permeability.

To solve the powerhouse intake high slope stability problem for the Xiaowan Hydropower Project a further comprehensive study was made based on the results of rock mass classification, sampling of soft seams, test and analysis, shearing plane network simulation and slope stability limit analysis developed in the early stage study .
