引言在岩基上修筑任何类型的大坝,均需彻底查明岩体的地质特性,因为这对于建筑物及其相联岩坡的稳定与安全将起关键的作用。设计者在充分了解了这些特性,并予见其危害因素之后,就能采取某些对策措施,以确保大坝与其围岩联成一体,使建筑物处于良好的状态。相应的处理方案,是在比较造价与安全的基础上,权衡得失审慎选定的。这类选择往往仍有 Introduction The construction of any type of dam on a rock foundation requires thorough identification of the geologic characteristics of the rock mass as this will play a key role in the stability and safety of the building and its associated rock slopes. After fully understanding these characteristics and seeing the hazard, designers can take some countermeasures to ensure that the dam is integrated with its surrounding rock to keep the building in good condition. The corresponding treatment plan is based on the comparison of cost and safety, weighing the pros and cons carefully selected. Often these options are still there
