Model test device capable of simulating foundation pit excavation under action of confined water and test method thereof
The invention discloses a model test device capable of simulating foundation pit excavation under the action of confined water and a test method thereof. The device comprises a model box, a water tank, a foundation pit supporting structure, a confined water head adjusting and monitoring system and a measuring system. In the test process, an external water tank is connected with a water inlet hole in the bottom of the model box to inject water, and a seepage field for simulating the confined aquifer is formed. The water injection function of the water tank device and the confined water head monitoring system are utilized to accurately regulate and monitor the water head change of the confined sand layer in the model box. The measuring system can record data in real time so as to obtain the response rule of the bending moment and deformation of the enclosure wall and the aquitard pore water pressure under the conditions of different excavation depths and water heads. The test has the advantage of low cost, and has a wide application prospect in practical engineering. Through the test method, the influence of foundation pit excavation on surrounding soil and structures can be deeply understood, the design scheme is optimized, and the construction safety and the engineering quality are improved.
本发明公开一种可模拟承压水作用下基坑开挖的模型试验装置及其试验方法，该装置包括模型箱、水箱、基坑支护结构、承压水头调节监测系统和量测系统。试验过程中，通过外部水箱连接模型箱底部的进水孔注入水，形成一个模拟承压含水层的渗流场。利用水箱装置的注水功能和承压水头监测系统，可以精确调控和监测模型箱内承压砂层的水头变化。该量测系统能够实时记录数据，从而获得不同开挖深度和水头条件下，围护墙的弯矩、变形以及弱透水层孔隙水压力的响应规律。这项试验具有成本低廉的优势，并且在实际工程中有着广泛的应用前景。通过这种试验方法，可以深入理解基坑开挖对周围土体和结构的影响，优化设计方案，提高施工安全性和工程质量。
