岩土体渗透性参数现场快速测试系统开发
DEVELOPMENT OF RAPID FIELD TEST SYSTEM FOR DETERMINING PERMEABLE PARAMETERS OF ROCK AND SOIL MASSES
【摘要】 基于单井内水流运动的振荡原理,开发了用于岩土体渗透性参数现场快速测试的系统(HSZK–01),使现场快速、高效测试岩土体渗透性参数成为可能。概要介绍该系统的功能、构成和现场操作步骤。基于变频水头测试仪(HGW–01)得到的数据,运用VB语言开发了数据处理软件,实现数据处理和参数计算自动化。本测试系统不仅能快速、准确地测定岩土体渗透性参数,而且对地下水及周边环境几乎不造成任何影响。在同一试验井内分别进行振荡试验和抽水试验,采用多种方法计算参数,发现两种试验结果基本一致;计算求得的参数值在同一数量级,表明该测试系统的可靠性和计算理论的准确性。
【Abstract】 A rapid field test system(HSZK–01) is developed to determine the permeable parameters of rock and soil masses based on the oscillating principle of fluid movement inside a single well,which makes it possible to obtain hydrogeological parameters quickly.The functions,frames and field operating procedures of the test system are introduced.Based on the Visual Basic language,a processing program is compiled to manipulate data obtained by variable frequency instrument(HGW–01);and the relative coefficients are acquired automatically.High-grade parameters can be determined in a short time.Furthermore,the effect of this test system on groundwater and its surrounding environment is free while working.Both slug test and pumping test are conducted in the same well;and the test data are analyzed using various methods to obtain the permeable parameters.The results are in the same order of magnitude and show a good fitness,which verify the reliability of the test system and the accuracy of the theory.
