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。Rigid seepage flow model box and earthquake simulation shaking table were used to explore water level response of well-aquifer system on shaking condition. The results showed that test box was fixed well on the shaking table, and boundary effect was not obviously. On the same vibration conditions and different confined aquifer characteristics, response characteristic of well water levels were different.Amplitude of well water level of the bigger cinfined and non-drainage condition aquifer was less than the smaller cinfined and drainage condition aquifer, but changes speed fast. And different response morphology including rise quickly-down slowly and rise slowly-down quickly. This tests could provid test basis for successive test of exploring law of water level response of seismic. At the same time, the shaking table test techniques of well-confined aquifer were discussed and technical experiences were provided for the same kind tests.
