中文摘要：

结合泰州长江公路大桥南、北锚碇沉井排水下沉工程,在现场开展了传统的常规抽水试验和基于自主研发的岩土体渗透性参数现场快速测试系统的微水试验以确定场区含水层渗透性。通过计算结果的对比分析表明,抽水试验法和微水试验法计算结果基本一致,但由于微水试验法具有试验周期短、成本低、设备简单、分层测试、无污染的特点。因此,与其他技术如抽水试验、示踪试验和实验室渗透试验相比,微水试验法有其独特的优越性,而且其精度与准确度完全能够满足实际测定含水层渗透性的需要,在确定含水层渗透性方面具有良好的应用前景。

英文摘要：

Combined with the south and north anchorage caisson drainage sinking project of Taizhou Yangtze Bridge, the conventional pumping tests and the slug tests based on the independent study and development of the rapid field test system for determining permeable parameters of rock and soil masses are carried out to determine the field permeability of the aquifer. Through the comparative analysis of the calculation results, it is indicated that the calculation results from the pumping tests and the slug tests are basically consistent, but slug tests are of the characteristics with the short testing period, low cost, simple equipment, hierarchical testing and no-pollution. Compared with other techniques such as the pumping test, tracing test and laboratory permeability test, the slug test has its unique superiority, and its precision and accuracy can meet the actual needs of the aquifer permeability testing, The slug test will has a good application prospect.
