STUDY ON THE CHARACTER ISTIC OF LANDSLIDE THRUST AND EVALUATION ON THE EFFECTIVENESS OF LANDSLIDE CONTROL

How to determine the landslide thrust is one of the most important basis for choosing the control project,and how to calculate accurately is always a tough problem for technicians as the different developing stage of landslide and the strength character of different place slip of landslide varies.How was the effectiveness of landslide control after the anti-slide construction has been build?In the paper,on the basis of in-situ survey and model-simulation of landslide thrust,the force distribution rule of retaining walls & retaining piles with prestressing cables are analyzed.Then,the curves of landslide thrust-time of retaining walls & retaining piles are discussed.Moreover,the effectiveness of landslide control is evaluated by the characteristic of landslide thrust.
