我们在火力发电厂厂址选择及勘测中,多次涉及到断裂的影响问题。下面就三个工程实例,亦大体属于三种情况,阐述如下。一、对 D-电厂断裂的评价D-电厂区地震基本烈度高(8度),且正处于地震活跃期。选厂阶段,于1973—1975年进行了三次物探工作,均证明有隐伏断裂存在。1978年经地球卫星像片解译后,再次进行地震法勘探,得出如下结论;(1)工区地下有厚3000米的第四纪和第三纪地
We have repeatedly involved the issue of fracture in site selection and survey of thermal power plants. The following three examples of projects, but also generally belong to three cases, set out below. First, the assessment of the D-power plant fault D-power plant area of high seismic intensity (8 degrees), and is in the active phase of the earthquake. During the plant selection stage, three geophysical workings were carried out in 1973-1975, both of which demonstrated the existence of hidden faults. After the earth satellite image was interpreted in 1978, the seismic prospecting was conducted again and the following conclusions were drawn: (1) Quaternary and Tertiary Periods with a depth of 3,000 m
