Test Study In Situ For Specific Property Of Infiltrating Loess

This paper is an important part of the scientific project <>(No.598780401) and the project of western transportation science & technology <> (No.200131881214). Based on large pooling infiltration testing of loess in situ, the characteristic of the infiltration of typical loess is discussed initially.The infiltration test of loess in situ is located on the testing spot of XinZhuangLing Tunnel of the ChanLiu Highway, where plenty of testing data is collected with TRIME Data Pilot and Soil Moisture Probe type SMS2 and Meter type HH2.Based on the analysis of literatures about slumping loess and infiltration theory ,a pooling infiltration model of the unsaturated loess soil is advised to compute the infiltration field.A management system of test is developed with the programming technology of Visual C++, Microsoft Access and Matlab, which becomes a strong assistant of large infiltration test of loess in situ, because it helps to collect accurate,integrated and reliable test data.The imitation and analysis of the infiltration property is accomplished with the programming technology of Matlab and Visual C++.
