Abstract


With the implementation of the development strategy of the rapid development of China 's road transport undertakings and the Bohai Economic Rim , as key areas of Tianjin future development , road construction of Binhai New Area is bound by leaps and bounds . Soft ground treatment and more problems with the construction of the highway , has become affect the quality of the project , the construction period , and one of the key factors of the project cost . Therefore, the strengthening of the soft ground treatment technology evaluation and optimization methods research has important theoretical and practical significance . Tianjin Binhai New Area road soft ground treatment technology evaluation and optimization system study , the main research work can be summarized as the following aspects : ( 1 ) research and access to information at home and abroad , Tianjin , Tianjin Municipal Engineering design and Research Institute of the design over the years by the research data , the results were collected and pooled analysis . (2) has been built on the Tianjin Binhai area typical road soft ground treatment site engineering survey . ( 3 ) as the theoretical basis to systems engineering , fuzzy math , the evaluation of the level of the soft ground treatment technology and road operators introduced in the evaluation index uneven settlement of the soft ground section of the lane , and that the service level , so as to establish a multi-level fuzzy evaluation model soft ground treatment technology for the Tianjin Binhai New Area road . (4) evaluation model established through the application of this article , the district three typical road soft ground treatment technology , test the reasonableness and accuracy of the evaluation model , and according to the results of the evaluation , model optimization suggestions . ( 5 ) through the investigation and evaluation of the soft ground treatment technology , the design process more cement mixing pile in soft foundation treatment in the Tianjin Binhai New Area road optimized to establish the optimum design model constraints Settlement and the application of research results on soft foundation treatment technology demonstration project to make the optimization .
