| Earth and rock-fill dam is a kind of ancient,made of stone and soil retaining structure [1].The damaging instances due to seepage flow gradually reduce,but due to uneven subsidence result in dam body producing larger crack,which commonly can cause dam collapse.For large earth-rock dam,a set of relatively perfect detection system guarantees the safety of operation of the dam,and for small and medium sized dam due to reasons,such as economic benefit monitoring system may not be so perfect.With the development of water conservancy construction in China,we explore a kind of having the effect on the settlement of practical engineering calculation method of the simulation of mathematical model,and it is very important to reduce the cost of late earth-rock-fill dam operation management.So exploring the analog calculation method is more particularly urgent.Therefore,innovation point of this article is based on the engineering example,using the elastoplastic model Drucker Prager-elastoplastic to analyze the earth and rock-fill dam.For engineering example using PROE model,using the powerful analysis function of ANSYS analysis software calculation of three-dimensional finite element modeling was deduced under the concept of cumulative settlement.After the building subsidence monitoring,it checks between the two.Compared the practical calculation results by ANSYS with the actual monitoring data,it proves that the results of elastic-plastic model in ANSYS Drucker Prager model are in good agreement with the calculated results of the actual monitoring and the calculation accuracy satisfies the requirement of practical engineering.The calculated results are appropriate,and the distribution trend of displacement gradient is reasonable.Therefore,this paper provides the theoretical basis for similar problems in the future,it has a guiding effect on the quality control of the landfill,and for the safety of the earth and rock-fill dam is also of great significance. |
