Optimal Selection Of The The The Xunyang Party Xiangjiaba Landslide Comprehensive Analysis And Evaluation, And Prevention Programs

Landslide as one important branch of slope calamity is largely involved in the hydraulic electric engineering and railway, highway, mining etc. The instability of slope as the general project question has been always paid attention to by domestic and international scholar. The need of study on stability and deformation mechanism is exigent, seeking rational and effective measure of landslide support is particularly important in the project practice.This thesis based on the control engineering of Dangjiaba landslide at Xunyang county in Shanxi province, the stability, engineering design, construction scheme are studied in this paper, engineering management scheme are studied in this paper. It provides some experimental and theoretical basis for further studying in this field. Main points are shown as follows:(l)The areal geology, hydrogeology, engineering geology and mans activity are investigated about the Dangjiaba landslide. The disaster of landslide is evaluated.(2)Through examination and site investigation, and combine pioneering data, the origin is systematically analysized. The paper put forward that the own factor of rock about litthology and geological structure are intrinsic factor, natural conditions and mans activity are extrinsic factor.(3)The development process is studied; the stability of landslide is analyzed by transfer coefficient and method FEM. Moreover, calculates the rock structure character and the thrust acting on the landslip on the basis of which a tentative preventative program is put forward.(4)Then analyze the internal force testing results, in order to judge the slope stability and reinforce impact. Next, the thesis remarks on the designing and computing methods, give the more reasonable methods for computing internal force. And the influencing factors of anchor cable prestress loss and the methods to decreasing the prestress loss are discussed. Basised analyses mentioned above, according to landslide cause of the formation and factors that influence thelandslide stability, this paper give some dispose project and feasible control engineer measures for landslide prevention and elimination.
