摘　　要：基于原位瞬态压力脉冲法原理及求解方法,研发了由数据采集控制系统、脉冲压力施加系统、测杆系统3部分组成的小尺度原位瞬态压力脉冲渗透性测试系统(已获国家发明专利[1])。该系统结构简单、易于控制、使用方便,可用于快速原位测量核废料地下处置、能源地下储存和深埋等地下工程中低渗透围岩的渗透率以及测试空间狭窄和岩体扰动要求严格的其他工程岩体渗透率。利用该系统实施了原位瞬态压力脉冲渗透率测量试验,试验结果验证了该系统的适用性、稳定性和准确性。Based on the principle of in-situ transient pulse technique and its solving method,the small size in-situ transient pulse permeability measurement system,including data acquisition control system,pulse applying system,and permeability measuring system,has been developed successfully.Due to its simple configuration and small size,it is easy to control and use to measure the permeability of low-permeable in-situ confining rocks rapidly,which are often studied in geological disposal of radioactive waste,underground gas and oil storage tanks and construction of deep cavern groups,etc.Moreover,other kinds of rock mass within narrow surrounding spaces or serious disturbance requirements also can be measured.The small size in-situ transient pulse permeability measurement experiments have been introduced in this paper by using this system,of which the applicability,stability and accuracy have been proved.
