摘　　要：区域应力场是构造运动的驱动力,是地壳应力研究中的重要内容,现今构造应力与地质资源的储存、开采及基础建设工程的设计实施具有密切联系。文章对锦州南部地区9个钻孔进行了翔实的现场水压致裂原地应力测试,并依据强度与应力指标,对应力状态和岩爆风险分别进行了评价与预测。结果表明,测区最大和最小水平主应力量值分别为3.92~17.33 MPa和3.00~8.93 MPa,垂直应力值为0.80~4.58 MPa,最大水平主应力方向在N33°~88°E之间,优势方位为N72°E;地应力评价结果显示为低~很低应力状态,工程区地下厂房附近无岩爆风险。Regional stress field is the driving force of tectonic movement and an important part of crustal stress research.Nowadays,tectonic stress is closely related to the storage and exploitation of geological resources and the design and implementation of infrastructure engineering.The detailed on-site hydraulic fracturing in-situ stress test is carried out on 9 boreholes in southern Jinzhou,and the stress state and rock burst risk are evaluated and predicted according to the strength and stress indicators.The results show that the maximum and minimum horizontal principal stress values in the survey area are 3.92-17.33 MPa and 3.00-8.93 MPa respectively,the vertical stress value is 0.80-4.58 MPa,the maximum horizontal principal stress direction is between N33°and 88°E,and the dominant direction is N72°E;the results of crustal stress evaluation show that the stress state is low to very low,and there is no rock burst risk near the underground plant house in the engineering area.
