对乌鲁木齐市蔬菜副食品总公司酿造厂场地内雅玛里克活动断层的精确定位和活动性判定工作进行了讨论 ,确定了雅玛里克断裂为全新世早期活动断裂 ,倾斜速率为 0 .2 6～ 0 .37mm/ a。该断裂现代仍有小量级地震活动 ,目前主要以蠕滑为主 ,属中等全新世活动断层 ,场地内不宜进行重大工程建设。并确定了雅玛里克南支断层破碎带宽度小于 15m,其上盘影响带宽度为 35m。与前人工作的结果进行对比差别是明显的 ,为此从单体工程设施安全性和城市土地规划经济合理性方面探讨了活动断层精确定位工作的意义和重要性。
The precise positioning and activity determination of the Yamalik active fault in the brewery site of Urumqi Vegetable Vegetable Processing Corporation was discussed. It was confirmed that the Yamalik fault is an active fault of Early Holocene with a tilt rate of 0.2 6 ~ 0.37mm / a. There are still some small-scale seismic activities in this fault. At present, it is mainly creeping-slip and belongs to the mid-Holocene active faults. Therefore, it is not suitable for major construction projects in the site. And it is confirmed that the width of the crushed zone of the southern branch of Yamalik is less than 15m and the influence width of the upper plate is 35m. Compared with the results of previous work, the difference is obvious. Therefore, the significance and importance of precise positioning of active faults are discussed in terms of the safety of single engineering facilities and the economic rationality of urban land planning.
