Research On Foundation Treatment Depth And Scope Of Shanxi Deep Collapsible Loess Venues

With economic development, there is more and more engineering constructionprojects on the majority of deep collapsible loess ground in Shanxi, because ofcollapsible soil is deep often a multi-storey building to do ten meters or more thickfoundation treatment in order to meet Code for building construction in collasible loessregions for the remaining collasible requirements,the high cost of foundation treatmenteven more than the upper structure, which is extremely unreasonable. It need to dealtwith such a thick wet soil collapsibility or not, how to determine the depth and scope offoundation treatmentmore is more scientific and reasonable, that become a veryimprotant problem in Shaanxi deep collapsible loess site engineering construction needto be solved.The paper is based on Agricultural resources agricultural machinery accessoriesmarket project of Zhongnong Group in Fuping, according to numerical simulations andtheoretical calculations.(1)Consider the artificial foundation as a whole lump after all being treated.Assume that the collapsible soil separate from the artificial foundation above after thepart under the foundation collapsed with soaking, then dig it through a empty model andanalyse the impact on the artificial foundation with change in collapsible area.According to analysis results, compare the largest collapsible area with collapsible areawith soaking and then analyse the depth of foundation treatment.(2) Consider pile composite foundation as a vertical reinforcement after partialbeing treated. Then assume that untreated soil surrounding hang on the pile compositefoundation after collapsibility and analyse the impact on foundation treatment range with pulling force existed.On the base, the paper believe that the Shaanxi deep collapsible loess venuefoundation on the basis of taking into account the artificial foundation itself must resistcollapse deformation as well as part of the deal with the foundation has ability to resistthe surrounding soil collapsibility is not dealt with all for further research related issuesplay a reference role.
