变形体的稳定性及其定量分析方法初探

变形体的稳定性是变形体性质的重要内容，它是工程实际中极为关注的问题，但从变形监测的角度上来分析变形的稳定性目前在国内外还未见任何实质性的报导。本文讨论了从变形监测角度上分析变形体稳定性的一般方法，进行变形稳定性的分类，初步研究了变形体稳定性的定量分析方法，定义了一系列量化指标，如稳定度、因素的影响域与因素的稳定域等。这些有利于把稳定性分析推向应用和深入，从而提高变形监测在变形体定性分析中的地位，增

STABILITY OF DEFORMATION OBJECT AND PRELIMINARILY STUDYING ON ITS QUANTITATIVE ANALYSIS

The stability of a deformable object is an important content of its character of the object, which is much interested in engineering. No material report is found in internal and external issues which analysis the stability of an object with monitoring data. In this paper, we present some general methods for analyzing the stability from the angles of deformation monitoring, and classify the stability of an object. Furthermore, we preliminarily study the quantitative analysis methods by defining series of values such as stability degree, influence range of an influence, stable domain of influences. Which is advantage that we put the stability analysis an application and deeply study it, therefore raise the status of deformation monitoring in the stability analysis and the ability in solving the practical problems.
