Class Soil Slope Frame (beam) Computing Model Study Of Internal Forces

This paper has developed comparatively systematicly on the foundation of collecting firsthand information in large quantities, is for the frame of prestressing force of anchor cable (land beam) the mechanism research with side slope interaction, through the way theoretical analysis and field test aim at reaching the calculation with reasonable force in frame (land beam) pattern. Through the information that collected, analyse the assupmtion of frame (land beam) that gets force property and puts forward frame (land beam) to get force pattern; Through field test study frame (land beam) force distribution law, and then reach reasonable calculation pattern, in order to guide the design of this kind of project; Know to count the force distribution law in value calculation and analysis.For 3 kinds of above method go on for score Xi, Winler flexible foundation beam calculation the actual work that pattern can reflect component better state, at the same time make calculate result since it has neglected the role of the deformed base huge friction obstruction of mechanical resistance in safety, therefore can think this pattern calculation the frame of anchor cable (land beam) force comparison ideal.When the length of beam is less relative to rigidity, (beam the high span of anchor cable Zhi than is larger than 1/6, for instance the beam of frame), the calculation of Winker flexible foundation beam law result with pour beam law is close to, right now simplify to pour beam law calculation influence do not be too big.Though Winkler flexible foundation beam calculation pattern can reflect component greatly force distribution, but it neglects the role of following factor, the minute that force and anchor cable face as bottom friction along slope force and component bury to put the space-time variation that depth as well as rock earth turn over force coefficient, make calculate result still in conservative. Suggest that later research work should be comprehensive to consider the couple role of above factor, reach more perfect reasonable calculation pattern.
