摘　　要：文章以深圳市某场地为案例,通过开展微水试验,运用Hvorslev模型估算了观测井所在含水层的渗透系数,并深入分析试验影响半径、井半径以及进水段长度等参数的敏感性。研究结果显示,当影响半径小于0.1 m或滤管长度小于1 m时,这两个参数对渗透系数的估计具有较高的敏感性;而井半径在各种情况下均对渗透系数的估计产生显著影响。Taking a site in Shenzhen as an example,this paper estimates the hydraulic conductivity of the aquifer where the observation well is located by using Hvorslev model through slug test,and deeply analyzes the sensitivity of the parameters such as the influence radius of the test,the radius of the well and the length of the water inlet section.The results show that when the influence radius is less than 0.1 m or the filter tube is less than 1 m,the two parameters have high sensitivity to the estimation of hydraulic conductivity.The radius of the well has a significant influence on the estimation of hydraulic conductivity in all cases.
