本文在阐述了声发射（简称ＡＥ—ＡｃｏｕｓｔｉｃＥｍｉｓｓｉｏｎ）法测量古构造应力的可行性之后，着重介绍了测量古应力与测量现今应力在方法上的不同之处。作者采用ＡＥ法测量了塔里木盆地北部油田古应力，并得出该区喜马拉雅期有２幕主要构造运动；燕山期有３幕主要构造运动；古生代有２—３幕主要构造运动的认识。喜马拉雅构造运动在该区占主导地位。
After elaborating the feasibility of measuring ancient tectonic stress with AE-Acoustic emission method, this paper mainly introduces the differences between the methods of measuring ancient stress and measuring the current stress. The authors measured the paleo-stress of the northern Tarim Basin by AE method and concluded that there are two main tectonic movements in the Himalayan period, three main tectonic movements in the Yanshanian period and 2-3 main tectonic movements in the Paleozoic. The Himalayan tectonic movement dominates the area.
