问题 单项选择题

水利水电中小型工程与大型工程在初步设计阶段工程地质勘察要求上的区别是()。

A.勘察的任务和内容有所不同,勘察工作量及工作深度和精度也不同

B.勘察的任务和内容有所不同,勘察工作量及工作深度和精度相同

C.勘察的任务和内容相同,勘察工作量及工作深度和精度有所不同

D.勘察的任务和内容相同,勘察工作量及工作深度和精度相同

答案

参考答案:C

解析:中小型水利水电工程初步设计阶段的勘察任务和内容与大型工程基本相同,只是因工程规模较小,勘察工作量及工作深度和精度不需要达到大型工程那样的程度。本阶段的水库区勘察只针对存在的主要工程地质问题进行,坝址区、引水线路、排水线路及其他建筑物区勘察结果应能满足各建筑物设计的要求,并为最终确定坝型、建筑物轴线的确切位置,以及确定各建筑物的建基面高程和地基处理方案提供地质资料与建议。对于一般性的地质问题,可在施工期间随地基开挖而解决。
