利用跨断层水准测量资料，结合长水准测量成果，重点分析了沂沭断裂带及其附近地区垂直形变特征及本区中强地震前异常形态。结果表明：沂沭带附近的地壳形变明显受新构造活动的控制，断层的最大垂直运动速率为０５０ｍｍ／ａ，沂沭带断层垂直运动平均速率合成值约为０３４ｍｍ／ａ，现今总体活动水平较低；沂沭带北段及北西向断裂近期呈反向运动，南段呈继承性构造运动，部分测点在本区中等及中强地震前异常较典型，主要异常形态为“Ｕ”或“Ｎ”型。
Based on the cross-fault leveling data and long-term leveling results, the vertical deformation characteristics of the Yishu fault zone and its vicinity and the anomalies before the moderate-strong earthquakes in this area are analyzed. The results show that the crustal deformation near Yishu belt is obviously controlled by neotectonic activity. The maximum vertical movement rate of fault is 050 mm / a, and the average synthetic velocity of Yishoutai fault is about 0.34 mm / a The overall activity level is relatively low; the north section of Yishu Belt and the northwesterly fault have been in reverse movement recently, and the southern section has a succession of tectonic movement. Some of the measuring points are anomalous before the moderate and moderate-strong earthquakes in this area, with the main anomalous morphology being “ U ”or“ N ”type.
