分层总和法在某建筑地基沉降预测中的应用与分析

Application and Analysis of Layerwise Summation Method in Ground Settlement Prediction of One Factory

建筑地基沉降是岩土工程领域的一个难点,在建筑设计和施工前常要预测建筑物的地基沉降,从而采取措施将建筑地基沉降控制在规范和设计要求的范围内,现常用的地基沉降计算和预测方法是分层总和法,本文介绍了分层总和法的原理,并运用于某具体的厂区分段堆场、钢料堆场、部件工场、切割工场的地基沉降预测计算中,通过沉降实测值与沉降预测值对比,表明分层总和法能很好地运用于场地地基沉降的预测。

The settlement of building foundation is a difficult point in geotechnical engineering. It is often necessary to predict the foundation settlement of the proposed building before design and construction, so as to take measures to control the settlement of building foundation within the scope of specifications and design requirements. The commonly calculation and prediction method of foundation settlement is layerwise summation method. This article introduced layerwise summation method and applied it to the calculation of floor settlement in a specific plant, such as sectional storage yard, steel yard, component workshop and cutting workshop. By comparing the measured settlement with the predicted settlement, the results showed that the layerwise summation method can be well applied to the settlement prediction of the site.
