Analysis & Model Tests On Behavior Of WJP And Its Composite Foundation By Changing Soil And Temperature Parameter

WJP composite foundation is one of the most widely used groundwork improvement techniques in the highway construction applications. It is widely used in the sections of the highway on bad geologic conditions. Although academia and engineering are always working hard on the technique and its interior problems, the technique is still need to be improved and its problems are need to be resolved when facing the complicated problems, various conditions and localizations of identifying the problems. The essences of the thesis are to quantitative research on the model WJP and Its composite foundation by changing soil and temperature parameter. Clinging to the background of the construction of the Lian-Yan highway, it can distill more practice data, more associational information and more comparing methods of analysis.The emphasis of the paper are focusing on the research of the model WJP composite foundation's displacement movements resulted in the soil characters changing and the model WJP non-confined compression strength variety by changing soil and temperature parameters.Via the indoors model tests simulating the realistic projects, the cores of the tests are exact emersion of the process of making piles and the environments of the WJP composite foundation. Basing a lot of different indoor model tests and the Similar Theory, research can attain the gist of contrast and analysis on the model and practice both sides. Now list the key works of the article bellow:(l)Surveying indoor model tests , temperature change to wet to gush out become and macroscopical variation tendency and quantization characteristic of microcosmic that intensity influence, and in wet to gush out become a course reliance situation to temperature; And according to test achievement person who improve field temperature change to wet to gush out become and theory that intensity influence analyse, propose the ground field temperature change to gushing out the quantization index of a intensity influence wetly finally.(2) To gushing out a research which becomes a quality wetly in the soil layer change , pass indoor experimental study, is it influence wet to gush out become and main factor that intensity turn into , carry on theory analysis and experimental study to main factor to analyse, it is main to be understand by factor change to gushing out because there aren't, proposing to the wet to last of quantization index , intensity of influence soil layer in mechanics index change for the physicses finally wet, offer the related design computing technology for the fact that the project is used. So, this model test has very important practical background of project and higher dependence.
