摘要综合论述水压致裂地应力测量理论和技术的发展过程，讨论基于推拉阀控制的单管加压系统或由外置式高压软管与钻杆组成的传统双管加压测试的水压致裂技术及适用条件。针对滇中引水工程勘察阶段大量采用绳索取芯钻探技术进行复杂地质条件地质勘探的实际情况，以绳索取芯钻杆条件的岩体地应力测试为研究对象，研究一种新型绳索取芯钻杆内置，并分段固定式双管水压致裂地应力测试方法，研发相应试验测试装置，对测试过程控制以及相应管道压力损失估算等进行研究和讨论。利用该项技术成功进行5个测孔56个测段的地应力测试，最大测试深度为724 m。该测试方法解决了传统水压致裂地应力测量方法不能直接应用绳索取芯钻杆的难题，对复杂条件下的工程岩体地应力测试问题提供了一种新的测试技术手段。

Abstract：The theoretical and technical developments regarding the hydraulic fracturing measurement of rock stress were reviewed firstly. Two hydraulic fracturing methods，including the single drilling pipe based measurement method and the traditional double tubes based hydraulic fracturing method consisting of an externally strapped hydraulic pressure tube and a drilling pipe，were discussed regarding the measurement process features and the application conditions. The wire-line core drilling technique was preferentially used for the geological investigation in the water transfer project at Dianzhong in Yunnan Province，China，due to complicated geological conditions. A new method of hydraulic fracturing measurement of rock stress with double tubes internally installed and sectionally fixed in the wire-line core drilling pipes was proposed to satisfy the special features of the wire-line core drilling technique. The development of corresponding system of equipment operation，the regulation of measurement process and the estimation of possible pressure loss along the hydraulic pressure tubes were studied. Finally，the proposed hydraulic fracturing method was implemented in 5 boreholes with 56 sections of measurement and the maximum depth being 724 m. The measurement technique proposed in this paper resolves the challenging problem that the wire-line pipes cannot be directly used in traditional hydraulic fracturing method，and provides a new technique for rock stress measurement in complicated conditions.

Key words： rock mechanics engineering rock mass rock stress measurement hydraulic fracturing wire-line core drilling pipes double pressure tubes based measurement Dianzhong water transfer project
