| 摘 要： | 康普水利枢纽工程联合进水口边坡岩体开挖后揭露3组结构面,它们形成不利组合对联合进水口的安全构成威胁。第1组结构面为倾向坡外的缓倾角断层(F1),构成边坡岩体的底滑面;第2组结构面为顺层断层(F218),构成边坡岩体的后缘切割面;第3组结构面为NE向陡侧角断层(F27),构成边坡岩体的倾切面。根据地质构造条件分析认为,联合进水口上部不稳定岩体的空间形态为,右侧以F27断层为界;左侧以河谷切割的监空面为界,后缘以F218断层为界。文章根据联合进水口开挖后揭露的缓倾角断层及其与水工建筑物的关系,从影响边坡岩体的稳定因素入手,采用岩质边坡极限平衡理论计算出联合进水口上覆不稳定岩体的安全系数,为边坡处理提供科学依据。

| Abstract: | Three sets of geological structures were disclosed on the slope at the joint intake of Xinjiang Kang-Pu reservoir.combination of these structures shows a unstable trend,threatening the safety of the reservoir's intake.The first structure surface is a low angle fault(F-1) dipping outside slope,possibly slip plane when the slope failure.The second structure is a bedding fault(F-(218)) and it could be the rear edge of the unstable slope.The third is a steep fault(F-(27)) and it coulde be the lateral boundary of the slope.Further more,stability of the slope is quantitatively evaluated using the limit equilibrium method.According to the exposed low angle faults and their connection with the hydraulic constructions,and starting with the effective factors of the slope rockmass,using the limiting equilibrium theory of rock slope to figure out the safety factors of the top instable rockmass of the joint intake,and provid the scientific basis for treatment of the slope. |
