【摘要】 系统收集广东地区地下流体观测网水位和水温资料,归纳汶川8.0级地震引起的同震响应,研究其响应特征、响应时间过程、响应空间分布等。结果表明:不同区域的水位测点出现同震响应的比例存在差异;水位同震阶跃变化以下降为主,其阶升、阶降的测井在空间分布上存在分区性;响应灵敏性方面,水位明显高于水温;震级越大、距离测点越近的强震,水位出现同震阶跃响应的比例越高;水位同震阶跃响应的方向能在一定程度上反映测点区域所受的构造应力状态,汶川8.0级地震对广东地区的影响以张应力为主。更多还原

【Abstract】 The water level and water temperature data of underground liquid observation net in GuangDong areas are collected in the paper.The simultaneity earthquake response evoked by Ms8.0 earthquake in WenChuan is concluded.The response characteristic,the response process,and the space distributing of the response are also researched in the paper.The result indicate that the measure item proportion of the water level change in simultaneity earthquake shows definite space distributing characteristic.The steps change of the water level in simultaneity earthquake mainly shows decreased trend.The sub -area characteristic is existed in space distributing of the measure well which appears ascend or descend in step.The water level is higher than water temperature in evidence in response sensitivity.The appearance proportion of simultaneity earthquake step response in water level will be higher when the earthquake level is bigger and the measure point is nearer to the strong earthquake.The simultaneity earthquake step response in water level can reflect the construction stress in a certain extent in measure point aeras.The influence of earthquake in WenChuan in GuangDong areas is mainly tensile stress.更多还原
