| 摘 要： | 滨海火力发电厂工程主要包括厂区建筑、码头、管道、取排水、填海和贮灰场等工程。其主要面临着福建省海岸带构造运动、断裂及地震活动、港湾淤积、海底滑坡、软土地基、海底活动地貌、基岩不均匀风化以及人类工程活动等主要的灾害性地质因素。通过对这些因素潜在的致灾特点分析，提出了滨海火电厂地质灾害风险控制应包括选址阶段地质灾害风险回避、设计施工阶段地质灾害风险处理及运行阶段地质灾害风险监控等3方面。地质灾害风险评估是滨海火电厂地质灾害风险控制的首要任务。针对滨海电厂工程的特点，评估内容应着重于地质灾害危险性评估及易损性评估。选址阶段地质灾害风险回避主要是对构造不稳定的回避。地质灾害风险处理主要是电厂工程的基础处理及管道抗冲刷处理。电厂运行阶段地质灾害风险监控主要是对建筑物基础稳定性及海域冲淤变化的监控。

| Abstract: | The main engineering projects of the thermal power plants comprise of plant buildings, wharf, sea floor conduit, water taking and ejecting, retaining wall, and store of dregs, and they are up against the main geological hazard factors such as tectonics movement, fault and earthquake, estuarine deposit, soft groundsill, moving physiognomy of sea floor, ununiformity weathering of rock, and artificial engineering action, etc. By analyzing their potential hazard characters, the author proposes that the main risk controlling of geological hazards of thermal power plants must include the risk obviation at the stage of the site choosing, the risk treatment at the stage of designing and constructing, and the risk monitoring at the stage of running. The risk assessment of geological hazards is the principal task of the risk controlling of geological hazard. Aiming at the characteristics of the engineering projects of thermal power plants, the assessment must be emphasized on the fatalness and vulnerability to damage of geological hazards. The geological hazard risk obviation in stage of the site choosing is mainly to avoid the labilization of tectonics. The geological hazard risk controlling is mainly the foundation disposal of power plants projects and the resisting eroding of sea floor conduit. The geological hazard risk monitoring in stage of operation is chiefly to monitor the foundation stability of buildings and the changing of sea floor deposition. |
