Testing device for simulating cascade collapse of adjacent foundation pits caused by collapse of certain foundation pit
The invention discloses a test device for simulating cascade collapse of adjacent foundation pits caused by collapse of a certain foundation pit, and relates to the technical field of wall support foundation pit tests, the test device comprises a model box, the model box is filled with sandy soil, and a foundation pit continuous wall model used for simulating a plurality of foundation pits is embedded through the sandy soil; the foundation pit continuous wall model is arranged in the model box, a plurality of foundation pit supporting models are arranged on the foundation pit continuous wall model, a data monitoring system is arranged in the model box, the foundation pit continuous wall model is arranged in the model box to simulate a foundation pit group in actual engineering, and foundation pit collapse is caused by overexcavation in a foundation pit simulated by the foundation pit continuous wall model or pile loading on the outer side of the foundation pit. And data are recorded through the data monitoring system, so that effective test data can be effectively provided for a foundation pit cascade damage mechanism, a test technology and a test method are provided for foundation pit protection, and a foundation is provided for safety guarantee of urban infrastructures.
本发明公开了一种模拟某基坑垮塌引发邻近基坑级联垮塌的试验装置，涉及墙撑支护基坑试验技术领域，包括模型箱，模型箱内填充有砂土并通过砂土埋设有用于模拟多个基坑的基坑连续墙模型，基坑连续墙模型上设置有多个基坑支撑模型，模型箱内设置有数据监测系统，本发明通过在模型箱内设置基坑连续墙模型模拟实际工程中的基坑群，并通过在基坑连续墙模型模拟的基坑内超挖或者在基坑外侧堆载而引起基坑垮塌，进而引发相邻基坑级联破坏，且通过数据监测系统记录数据，能够有效为基坑级联破坏的机理提供有效的试验数据，为基坑防护提供了试验技术和方法，为城市基础设施的安全保障提供基础。
