City Foundation Pit Design And Optimization Methods

Purpose Aim at concrete building foundation pit engineering to pay to protect the structural design scheme to carry on excellent turn the sieving,making use of the measure of linear weight in themany targets ambiguous optimizing method ,draw up a set of the retaining and protecting for foundation excavation scheme to pay to protect the scheme excellent turn the flow process.Device Turn the retaining and protecting for foundation excavation designing and optimizing method to is divided into two steps,the namely the total scheme optimizing and the detail of the sum scheme optimizing.The total scheme is excellent to turn namely the basis concrete condition of the concrete engineering,drafting to pay to protect the scheme,The safety that concrete engineering to attain, Economy, time limit for a project and so on, making use of the measure of linear weight in the many targets ambiguous optimizing method sieving. From them select one scheme that is more superior.The detail is excellent to turn the design while satisfy the premise of support the structure safety,arranging the sum design parameter through a reasonable excellent turn,attainning to build the price most province.Result Jinan central hospital sewage disposal engineering practices the examination enunciation, through this method excellent to turn the design.The adoption" the measure of linear weight " certain soil nailing wall+ alighting water scheme,comparing with other schemes,economize to build price more than 45,000 yuans for the engineering,Economize the work expects more than 10 days.And the construction industrial art is simple.Come to an excellent turn the purpose of the design.This method is to go useful.Conclusion Here discussing the method for the concrete engineering excellent turn the design is simple but useful row and also discover in practice process.Abundant construction experience rising in use excellently turn design ,the process of flowprocess device very important action. Because at the beginning,is the scheme sieving regardless,the parameter selection,Or give power for various weight marks heavy.All can not get away from abundant construction experience.Therefore,rising construction experience to the better usage of this method is very important.
