Abstract

The invention discloses an indoor power drainage consolidation testing system and method, relating to an indoor rock mechanics testing system and method. The system is composed of shock load applying device, straining three-axis pressure room, stress and strain senor, dynamic resistance strain meter, floating engineering dynamic meter, PC, and pressure frame; and the method includes the steps: (1) according to the diameter size of a sample, drilling a bore along the axis of the sample in proportion, and filling fine sand into it; (2) placing the drilled sample in the pressure room for reversal pressure saturation; (3) installing the shock load applying device on a force transferring pole, and installing the stress and strain sensor for testing aperture water pressure, shock stress and axial strain; (4) using data collector to make dynamic signal collection, transmission and recording.

Description

Technical field [0001] The invention relates to an indoor rock and soil mechanics test system and a method thereof; specifically, it is mainly aimed at the dynamic drainage consolidation and reinforcement treatment of soft soil foundations, especially when the on-site test conditions are not available, the construction period is tight, etc., the invention is used It can effectively simulate the construction process of on-site dynamic drainage consolidation method to treat saturated soft soil foundation in the laboratory, and use the moment of impact load to collect and analyze the impact stress, pore pressure and deformation signals in the soil sample, and master the soft soil The dynamic response law under impact load has important theoretical significance and engineering practical value for the development of soil dynamics theory, the improvement of the soft soil reinforcement mechanism of dynamic drainage consolidation, and the optimization of on-site design and construction sc...
