The Research On Optimize Supporting Scheme For Deep Foundation Pit Of Zhengzhou Exhibition Hotel

The engineering project building is a not reversible process. For the plain put engineering into practice, we must pay attention to optimize support scheme for deep foundation, avoiding have damage to society and environment and unnecessary society or economy lose. With unceasing development economy and society in china, it need to take entire and go deep into analyse for choice deep foundation support scheme. So a more science and system and practical optimize method of deep foundation support scheme is needed.The optimize method of deep foundation scheme is used in china. The final purpose is synthesize optimize of chioced deep foundation support scheme. But index system isn't perfect now, how to optimize is compare concerned now. This thesis on the basis of research analyse factor of affect support, through contrast on several appraise index sysytem, inproving and building multiple echelons appraise model (include 5 second index 13 third index), using fuzzy synthesize appraise and AHP, using expert investigate method define weight of every item, building and computing appraise model of deep foundation support scheme of Zhengzhou Exhibition Hotel project, find the best optimize scheme of Zhengzhou Exhibition Hotel project base on the compute final.This thesis base on the system engineering theory, through the engineering example of optimize scheme of deep foundation support in Zhengzhou Exhibition Hotel project, using Fuzzy AHP method research optimize method of deep foundaton support, main research under several field.1. Through research on severel index system of deep foundaton support, build deep founation support scheme third index system.2. Using Fuzzy AHP method compute feature weight of every levels index, find out synthesize weight. 3. Base on the deep founation characteristic of Zhengzhou Exhibition Hotel project, build optimize scheme of deep foundation support index system by expert invertigate method building scheme index appraise matrix.4. This thesis is based on Zhengzhou Exhibition Hotel project, making appraise by Fuzzy AHP method and choicing the deep foundation support scheme. That guide engineering pracise. Base on the compute final, find that the method suit optimize scheme of Zhengzhou Exhibition Hotel deep foundation support.
