【摘要】 本文依托国家自然科学基金项目《黄土湿陷的大变形理论描述与数值仿真分析》(No．598780401)和西部交通建设科技项目《黄土的浸水特性研究》(No．200131881214)，通过大规模黄土原位浸水入渗试验，对典型自重湿陷性黄土浸水特性进行了试验研究，初步探讨了黄土浸水入渗特性的规律。 依托(?)柳高速公路新庄岭隧道试验工点进行黄土原位浸水试验，利用TRIME DataPilot和高精度土壤水分测量仪(HH2)等先进的测试仪器进行大规模数据采集。在总结前人有关黄土浸水入渗理论和渗流理论研究成果的基础上，引入了黄土浸水入渗计算模型。 针对大规模黄土原位浸水试验特点，运用Visual C++、Microsoft Access和Matlab组合编程，开发了试验数据综合处理系统，成为黄土原位浸水试验有力的辅助工具，大大提高了试验数据的准确性、完整性和可靠性。 运用Visual C++、Matlab组合编程，对新庄岭黄土原位浸水试验性状进行仿真分析。更多还原

【Abstract】 This paper is an important part of the scientific project <<Large-strain description and numerical imitation analysis for hydrocompaction of loess>>(No.598780401) and the project of western transportation science & technology <<Study on specific property of infiltrating loess>> (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++.更多还原
