双曲线法在某发电厂地基沉降预测中的应用

Application of Hyperbolic Method in Foundation Settlement Prediction in a Certain Power Plant

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 settlement. At present,the specification has the explicit stipulation to the foundation settlement calculation,but the foundation settlement calculation results and the observed results vary widely,and computational 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 between the calculation results and the measured results. This paper firstly introduces the basic principle 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 observation data obtained from the time of final settlement value relative error is small,suitable for engineering application results are obtained. In this paper,the future in- depth study of hyperbola method is of positive significance.
