北天山西部地应力测量

In-situ stress measurement in western North Tianshan

北天山西部地区是构造活动强烈的地震多发区,这一地区的地应力测量无疑对该区构造应力场及地震活动性的研究具有重要的意义,同时对该区的工农业工程建设也具有十分重要的实际意义。本文介绍了北天山西部伊宁附近的水压致裂法原地应力测量结果。迄今还未见有关该地区地应力测量的报道。

The western part of North Tianshan Mountains is a region of intense tectonic activities and frequent earthquakes. In-situ stress measurement in this region is undoubtedly of important significance for the study of regional tectonic stress field and seismicity, and of practical value for economic construction of the region. This paper presents the result of hydro-fracturing in-situ stress measurement nearby Yining in western North Tianshan, which is the first report of stress measurement in this region up to now.
