双曲线法在某发电厂地基沉降预测中的应用

摘要

在地基工程建设中，需要考虑地基沉降问题。目前，规范对地基沉降计算有明确的条文规定，但地基沉降的计算结果和实际观测结果相差很大，而且计算复杂。所以，有必要对地基沉降预测进行分析研究，从而找到简易的计算方法和途径，减小地基沉降的计算结果和实测结果的差距。首先介绍了双曲线的基本原理，然后叙述了某发电厂一期工程概况，最后运用双曲线法对该工程进行地基沉降预测。通过对长达6年的观测时间所得出的数据进行计算，得出的最终沉降值相对误差较小，得到了适合工程应用的结果。期望对今后双曲线法的深入研究有着积极的意义。%In foundation engineering construction , it is necessary to consider the foundation settle-ment.At present , the specification has the explicit stipulation to the foundation settlement calcula-tion , but the foundation settlement calculation results and the observed results vary widely , and com-putational complexity .So, it is necessary to analyze the foundation settlement prediction research , thus the calculation method and way to find a simple , reduce the foundation settlement of the gap be-tween the calculation results and the measured results .This paper firstly introduces the basic princi-ple of hyperbola , and then describes the first phase of a certain power plant , the hyperbolic method foundation subsidence projections for the project , through the six years for the computation of the ob-servation data obtained from the time of final settlement value relative error is small, suitable for engi-neering application results are obtained .In this paper, the future in-depth study of hyperbola meth-od is of positive significance .
