Research On Factors Influencing Bank Stabilization Of Wharf Engineering On The Soft Ground

The soft soil is a special type of soil that is widely distributed in our country’scoastal and estuarine plain, sharing such features as the high water content, the lowbearing capacity and the great deformation after loaded influenced by its cause andstructure, without effective treatment during the construction, it may lead to thestructure cracking or even unstable failure. With the rapid development of portconstruction in our country recently, the phenomenon of lacking of land resources isincreasingly outstanding, at present the reclamation and building wharf on the softground project has become an important means to solve the industrial land problem inmost port cities. As the core of economic development strategy in Tianjin Binhai NewArea, Tianjin Port is typical soft soil area, bank stabilization is the premise ofsuccessful wharf construction when built on the soft ground with complexengineering property, the critical situation of port development also makes thisproblem a key research issue in safe, economical and reasonable construction projects.In this paper, on the review of researching history and current situation of slopestability problem, the bank stabilization problem of representative Tianjin CoastalArea Wharf Engineering on the soft ground is posed, bank slope stability is analyzedfrom aspects of on-site monitoring data and numerical simulation calculationcombining with the wharf engineering example of Tianjin Port, some valuablesuggestions are provided for the future related construction project, the main contentsare as following:(1) Briefly introduced the geological characteristics in Tianjin coastal area andconstruction condition of wharf engineering on the soft ground, posed the bankstabilization problem, described the research methods and applications at home andabroad of this problem in detail.(2) Introduced main factors influencing bank stabilization of wharf engineeringon the soft ground, detailed analyzed the mode and degree of influencing factors fromthe theoretical side, and put forward optimization measures that can improve bankslope stability.(3) The on-site monitoring data statistics of various bank slope monitoringcontents was made, and simulated the bank deformation in actual working conditions by using the PLAXIS geotechnical finite element software, analyzed bank slopestability under influencing factors from two points of view separately, providedreference and guidance for actual construction.(4) According to the bank stabilization problem of wharf engineering in thecurrent, put forward some suggestions on decreasing unfavorable factors andincreasing favorable factors, and prospected further research of this problem.
