The Anti-cracking Analysis Of The Joint Based Constituted By Independent Foundation Add Waterproof Board

In recent years, along with the high-speed development of city construction and the contradiction of parking space between supply and demand increasingly serious, causing the foundation forms of contains the basement is widely adopted; In areas with better subsoil, including the basement garage multistory buildings and high-rise buildings podium, the designing based more and more adopted the foundation forms of the joint based constituted by independent foundation add waterproof board.This thesis is throughed to the analysis of based on waterproof board structure stress characteristics, design load, supporting conditions and calculation principle and so on, studied the new foundation forms of waterproof board structure design of related calculation theory.By using finite element ANSYS10.0 general-purpose software,simulating analysis the waterproof board structure finite element model, contraposing to the finite element model of waterproof board structure for the analysis of the different parameter,main parameters including the foundation forms in construction stage whole casting is waterproof board inside and outside temperature, use different stage of underground water level higher than in waterproof board of basement ground, waterproof board adopt different values and waterproof board thickness by different the ratio of reinforcement, etc; In order to analyze the different parameters impacting on the properties of the anti-cracking to this foundation forms.Finally, based on comprehensive analysis to the waterproof board structure finite element model simulation results of the joint based constituted by independent foundation add waterproof board, finding out the critical cracking temperature of the waterproof board structure to avoid or reduce waterproof board structure early cracks in concrete operation Suggestions produced forward; At the same time for waterproof board structure to identify the design appropriate plate thickness and look for a scope, the foundation forms the stress of the vulnerable points, Suggesting for the foundation design based on measures and the ratio of reinforcement.
