Based on unsaturated soil seepage and shear strength theory , to explore the pore pressure dissipation law , it has been analyzed seepage about slope of deep foundation pit in Xian , supporting by pile-anchor retaining structure under the condition of continuous rainy by MIDAS software . The simulation result shows a temporary saturated region would appear on the surface of slope in continuous rainy days , then soil water content increasing as the rainwater infiltrate into a deeper soil layer gradually .For the sake of different cohesion of different time , Combine moisture filed , coming from pore pressure field , with the functional relationship between water content and cohesion , of simulated with filed test dates .The influence law of continuous rainy is derived from stability analysis by strength reduction fem about slope safety factor and stress of retaining structure .
Rotary torque is one of the important parameters of the bogie. A scheme of the rotary torque test for the bogie was put forward, and the homogeneous matrix based on the Euler angle was introduced, the model of inverse pose of the slewing platform was built. Also, it implemented the real-time solution by means of simulink, and fitted the curve of hydraulic cylinder expansion amount and time by use of the MATLAB curve fitting toolbox. The method that took the motion curves of the actuators as the control input is put forward, which was of great value and laid the foundation for the test of rotary torque.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
