一断裂构造对工程建设的影响（First, the impact of fracture structure on engineering construction） First, the impact of fracture structure on engineering construction Fault and engineering construction, engineering construction, water conservancy construction and so on, must consider the fault structure. For example, the reservoir dam is not located in the fault zone, and Water Leakage so as not to cause other adverse consequences; large bridges, tunnels, railways, factories and other large or if the fault is located in, must consider the corresponding engineering measures. Therefore, any major project must have the geological data such as fracture structure in its area for reference by the designers. Engineering geological evaluation of faults 1. Mechanical properties of faults: faults formed by tension, and their engineering geological conditions are worse than those caused by pressure. But the pressure formed fault fracture zone width, and should be paid attention to; 2, the location of fault and line engineering, general line through vertical fault along the fault direction by the ratio of 3, small damage; fault occurrence and line engineering level: the fault line and the inclination angle is larger than 10o, engineering geological conditions; the occurrence and development of stage 4, the fault is: active faults (such as violent tectonic movement, earthquake prone areas, faults) influence on the engineering building, less influence some relatively stable, but the fault, should consider the possibility of resurrection, 5, water: full the fault of the water with poor stability; 6, human impact: some large reservoirs, the near fault reactivation, can not be ignored. Give an example The Jinjiang Yongan fault zone is strongly represented in the deep and shallow parts of the Quanzhou basin, and has a bearing on the engineering construction of Quanzhou city. Break the bad geological related to construction engineering construction should be carried out on the edge of the Quanzhou ba
