摘要
巴基斯坦SK水电站工程地处喜马拉雅褶皱带,地质条件十分复杂。在可行性研究和招标阶段,英国莫特麦克唐纳公司和法国柯恩贝利尔公司仅对浅表层开展了少量的地震波、电测深测试工作。在基本设计、详细设计及施工图设计阶段的勘测中,通过应用EH-4连续电导率成像系统、V8多功能电法仪系统、SIR4000探地雷达系统等国际先进的物探技术及设备,成功解决了诸如河床深厚覆盖层探测、地下厂房位置比选、右岸溢洪道边坡卸荷带深度探测、引水隧洞超前地质预报等一系列工程地质问题,在施工期开挖后均印证了物探成果的可靠性。实践证明,科学合理地运用物探技术可为工程勘察提供有效的技术服务和决策支持。
The SK Hydropower Project in Pakistan is located in the Himalayan fold belt,characterized by extremely complex geological conditions.During the feasibility study and bidding stages,Mott MacDonald(UK)and Coyne et Bellier(France)only conducted limited seismic wave and electrical sounding tests on the shallow surface.During the basic design,detailed design,and construction drawing design stages,by applying international advanced geophysical prospecting technologies and equipment,such as the EH-4 continuous conductivity imaging system,the V8 multifunctional electrical instrument system,and the SIR4000 ground-penetrating radar system,a series of engineering geological problems are successfully addressed.These include the detection of deep overburden in riverbeds,the selection of underground powerhouse locations,the depth detection of the unloading zone on the right bank spillway slope,and the advanced geological prediction of the headrace tunnel.The reliability of these geophysical prospecting work is confirmed during excavation in the construction phase.Practice has proven that the scientific and rational application of geophysical prospecting technology can bring significant technical support and decision assistance.
