The Coastal City Of Deep Foundation Pit Support To Explore

Deep foundation engineering in recent decades the practice, in terms of design, construction, equipment and techniques, or theory, technology and experience, have reached a very high level. However, with the social development and the spread of all kinds of corruption, the foundation pit supporting industries are slowly spawned some bad practice, I call it the "experience". Called the empirical method is to design entirely dependent on the software is almost no longer calculated by feel and experience design, and a lot of designers do not have any practical experience, so the problem is caused by too conservative design caused a lot of waste or existence than the quality risks. The science and practice through a rigorous calculation should be based on a variety of conditions and to design and organize construction.In this paper, a coastal deep foundation pit support engineering, for example, to start the survey report by the investigation unit, the detailed calculations of the combined support of soil nails and the whole process of the nursing program of combined pile and anchor pile anchor the soil nailingcomparative analysis to determine the best supporting program.The paper first analyzes the information provided by the survey report, and to the scene to conduct site visits, it was initially selected soil nailing wall pile anchor combined support of the combined support and soil nail wall and pile anchor three program be designed and calculated contrastselected one of the most economically reasonable solution.Then the paper examines the coastal cities of deep foundation pit support and related technical quality requirements down the drainage construction methods and quality requirements and construction monitoring.The last paper summarizes the coastal city of deep foundation projects from the survey need to pay attention and control, appealing to the action according to the standard deep foundation pit support of the professional design and construction, along with the entire process of excavation monitoring management in Chinaof deep foundation pit support level to a new height.
