Rock-soil static lateral pressure simulation device and effective stress calculation method
The invention discloses a rock-soil static lateral pressure simulation device and an effective stress calculation method.The rock-soil static lateral pressure simulation device comprises a first metering cylinder, a liquid inlet box, an experiment cylinder, a liquid outlet box and a second metering cylinder; a supporting structure is arranged at the top of the liquid inlet box and comprises a hydraulic oil cylinder and an axial force meter, the axial force meter is arranged at the top of the liquid inlet box, and a hydraulic rod of the hydraulic oil cylinder abuts against the axial force meter; a plurality of pressure sensors are arranged on the side of the experiment cylinder. According to the rock-soil static lateral pressure simulation device and the effective stress calculation method, the rock-soil static lateral pressure of remolded soil or undisturbed soil taken on site can be directly measured, the actual site situation of the rock-soil on the side of a foundation pit is directly simulated, and the test result of the static lateral pressure of the foundation pit is more accurate. Meanwhile, the traditional concept of the effective stress of the Taiwan foundation is broken through, a new effective stress calculation formula is provided, and support is provided for development of theoretical soil mechanics.
