摘要
根据大量的水利水电勘察资料和各方面的专题研究成果,证明大柳树坝址存在、大范围的松动岩体。这个问题的提出使得人们对大柳树复杂工程地质条件的认识有了一个质的飞跃。结构面张开、渗透性强烈是松动岩体的水文地质特征,它们将严重影响坝址防渗处理、高边坡开挖、渗透和渗漏稳定,将具有技术上高难度、经济上高投入、安全上难保证、决策上高风险等四大特点,所以要高度谨慎地对待松动岩体的渗透问题。
According to abundant prospecting data of irrigation works and hydropower stations and various reports of monographic study,it has been testified that there is relaxed rockmass over an extensive area at Dalushu dam site. It results in an essential leap in cognition process concerning complicated geological engineering conditions on Daliushu dam site. Both open structural surface and intensive permeability are the hydrogeological features of relaxed rockmass. Study is made on the treatment of permeable rockmass,excavation of high slopes,seepage loss and permeation stability of rockmass. The study results show that the project in such condition is of the features,such as higher difficulty of technology,huger investment,difficulty to safeguard,higher risk of policy making.
