Study On The Calculation And Optimization Of Earthwork In The Site Formation Construction Project

Grading is indispensable to any construction projects construction prophase,mainly includes the field leveling construction project caculation site design elevation,site earthwork allocation and the three venues caculation process,including site design elevation and location earthwork allocation is the precondition of field caculation.Therefore need to be in smooth construction project based on the introduction to the theory of engineering caculation,still have no from the field at home and abroad for grading design elevation calculation and site grading caculation method and earthwork calculation scheme these three aspects to study of smooth construction project caculation,strive for in grading design elevation of the field calculation optimization,optimization field leveling project caculation and earthwork calculation scheme optimization of the three breakthroughs.First of all,in this paper,the smooth construction project caculation of related theory,the traditional level,summarized the caculation method of construction project,and analyze the flat key construction project caculation,provide theory support for the research.Second,compared the traditional common ground,and a method for determining the design elevation using least squares optimization site design elevation of the smooth construction project engineering problems,in order to smooth construction project to provide the most accurate calculation basis caculation.Then,an overview of the smooth construction project engineering earthwork allocation optimization,the basic content of the comparison and analysis on traditional table solving method and the Matlab software to solve method in the application of earthwork allocation optimization scheme,the advantages and disadvantages in the selected optimal smooth construction project engineering earthwork mixing method.Contrast in the end,based on CASS software of two kinds of method,the advantages and disadvantages in the traditional field caculation with Jin Fu garden flat construction project as an example,study Jin Fu garden flat construction project site elevation of design optimization and site earthwork allocation optimization of engineering caculation results.The results show that the determination of the site design,the soil allocation of the site and the calculation of soil volume are the key elements in the calculation of earthwork of the site.Based on least square method,the optimal site design elevation calculation model,not only can meet the digging filling balance of smooth construction project engineering principles,but also ensure the earthwork digging filling quantity minimum time requirements,with traditional grid calculation method of incomparable superiority.Traditional table on solving method and the Matlab software to solve method can solve the flat construction projects of the optimum earthwork allocation,but USES the Matlab software can make the design of earthwork allocation efficiency.With least square method earthwork quantity calculation to optimize the design of the ground elevation can reduce project,earthwork allocation scheme was optimized by using Matlab software to solve method can shorten the project transportation distance,at the same time using the CASS components on leveling project earthwork quantity calculation method of DTM to calculate,has higher calculation precision,and not be restricted by terrain characteristics.
