The Software System Of Slope (Landslide) Control Design And Its Application

With the development of our country's foundation construction, the study and control design of engineering slope is becoming a hot topic. The thesis is about the software development of 4 plastic limit equilibrium methods and 4 control design methods, and its application on the control design at the west approach slope and landslide of Zhegu Mount. The achievements are these:(1) On the foundation of study the control design theory and methods, develop the software system of slope(landslide) control design(Slope-CDS version: 1.0). It include two children systems: the children system of stability analyses and the children system of control design. It can not only analysis the stability of slope and design the control design, but also have the capacity of fault-tolerant technique. It provide a quick and convenience measure for the west open development.(2)Study the 4 plastic limit equilibrium methods, such as Fellenius method, Bishop method, transfer coefficient method and plane linear method, and their program design. About the load, consider the vertical load, when under the action of water, consider the horizontal still water press, the press which erects to the surface of slide, and consider the effect of hydrodynamic load and earthquake.(3)The software about the frame design, apply the stiffening bar method and elastic foundation method to account the endogen. About the frame section, apply the trial method to define the list and potential section dimension, then distribute steels and check the calculation.(4)About anchor tie, the software applies two specifications for the user choice. According to the result, the software recommends the best steel dimension and the layout.(5)The software combines anti-slide pile with anchor wire anti-slide pile, apply the matrix analyses method to design anti-slide pile. And 3 anchor wires on the anti-slide pile. Then the software can draw out moment chart, shear chart, horizon displacement and turn angle.(6)The thesis puts forward the pile-top displacement control method, and it can account the least force of the anchor wire on anti-slide pile.(7)Application the authoritative example to test software's correct, the result is reasonable. The application on the control design at the west approach slope and landslide of Zhegu Mount is accepted.
