| With the rapid economic development of Binhai New Aera in Tianjin, municipalinfrastructure is also in a heavy construction. Binhai New Aear is widely distributed withsoft soil, how to build subgrade on the soft soil, and ensure its safety stability, efficiencyand rationality, become the key problems in road construction. Aiming at this problem,this paper has carried out the following works.Firstly, in accordance with the mechanism, classified the common method to softsoil subgrade treatment, evaluated the applicability according to different treatmentmethods in Binhai New Aear. Compared various treatment methods, reinforced cushionmethod stands out as priority soil subgrade treatment in Tianjin Binhai New Aera forabsolute advantages like saving investment, convenient construction, rich practicalexperience and short time limit of construction.Generally, the stability problem of municipal road is not prominent; the key is tocontrol the subsidence. Depends on3engineering examples of soft soil subgradetreatment in Tianjin Binhai New Aera, analyzed the influence factors of soft soilsubgrade treatment, studies the application of reinforced cushion method respectively inthe borrow pit section, fill out section, salt fields and shrimp ponds, discussed theinfluence factors of soft soil foundation treatment in Binhai New Aear; Put forwarddifferent treatment schemes according to the influence factors, and by the comparison oftechnology and economic, selected the optimal treatment; analyzed and predictedfoundation subsidence, determined the content and method of subsidence observation,and analyzed the observation results.Results in this paper with respect to the manner of municipal road engineering ofsoft soil foundation treatment have certain reference significance. |
