【摘要】：利用自行设计的刚性渗流模型箱,结合地震模拟振动台,初步探索了振动条件下井-含水层系统水位的响应程度。结果表明:试验箱与振动台固定良好,试验箱边界效应不明显。相同振动条件,不同含水层特征,井水位响应特征不同。承压性大的非排水条件的含水层水位响应幅度比承压性小的排水条件的含水层小,但变化速度快;同时会出现急升-缓降和缓升-急降等不同形态。此次试验可为后续探索水位对地震波响应规律提供基础。同时还探讨了井-含水层系统振动台模型试验技术,为今后开展此类试验提供技术经验。
[Abstract]:Using the rigid seepage model box designed by ourselves and the seismic simulation shaking table, the response degree of the water level of the well- aquifer system under vibration conditions is preliminarily explored. The results show that the test box and the shaking table are well fixed, and the boundary effect of the test box is not obvious. The response characteristics of well water level are different with the same vibration conditions and different aquifer characteristics. The response amplitude of aquifer water level in the high pressure non-drainage condition is smaller than that in the low pressure drainage condition, but the change rate is fast, and there will be different forms such as sharp rise, slow drop and slow rise and drop at the same time. This experiment can provide a basis for further exploring the response law of water level to seismic wave. At the same time, the shaking table model test technology of well aquifer system is discussed, which provides technical experience for developing this kind of test in the future.
