Technolgy Research On Assort With The Deformation Of Road Widening

Recently, along with the speedy development of the nationaleconomy, the highway freight volume has been rapidly increased,sinceperiodicity construct and cannot avoid to widen the old road,the qualityof the engineering is affect the benifit of the nation, the questiones ismust be resolved ,these include the control the quality of the design andconstruction, the deeply research on the theories or criterion,the difficultproblems such as the claw of widening road and disharmony ofsedimentation.The paper is relate the Zhu-Cheng Widen Road Project,setup a series of measures and some practicability technologies to controlthe quality on widening road.The paper is base on the project ofZhu-Cheng Widen Road, the method has been set up to control thedeformation of roadbed ,in the project some practical technique alsohas been used ,these bring into positive effect.firstly, start with the main problem of the engineering,analyse the oldroad status,expatiate the effection on four reasons that include thecondition of the groudstill,the type of the widening road,the quality of theroadbed,the load. the sedimentation and crack mechanism also has beendiscussed on the widening road;Secondly, relate to the instance,put forward a series of measures whichare the control on design and construction, experimentaion, reinforce ofthe roadbed or groundsill,observe on the deformation in the projectperiod.in the experimentaion a method to control the compactionness hasput forword,which include the interior soil test and optimization ofefficacy reach right compactionness by orthogonal test.the optimallime-earth mixing ratio has been confirmed by the interior test and fieldtest.In order to confirm the mechanics parameter of soil,the triaxialcompression test of soft clay ground and standard penetration test etc.had been done.Thirdly, some mathermatics model about the sediment-tation has beensummarized, using Matlab Software to program Gray VerhulstModel,Logistic Model and so on,the optimal model has been selectthrought contrasting these models' effection and verify these precision.Finally, the parameters on soil testing has been used in ANSYS Software to simulate the sedimentation, the reason of the diversitysedimentation has be indicated by numerical simulation. using themathermatic model to predict the different settlement, the result is meetthe controllable demand and the series measures that proved feasibility inpractice.
