地基固结沉降量的计算,前人已进行了长时间的、富有成果的研究,现有的计算方法也很多,目前使用较多的是压缩曲线法(e-p曲线法或e-logp曲线法。)该法的优点是计算简单,计算参数易于由试验取得;由于使用时间较久,积累了较丰富的经验。但与其它方法(数值法除外)一样,也存在一些缺点。首先,对于一个土层,若取不同深度的多个原状土样进行压缩试验,得到许多压缩曲线,而在计算时要选取一条有代表性的压缩曲线则比较困难。
The calculation of the settlement settlement of foundations has been carried out by researchers for a long time and with fruitful results. There are also many existing calculation methods. At present, most of the methods used are the compression curve method (ep curve method or e-logp curve method). The advantage of this method is that the calculation is simple and the calculation parameters are easily obtained from the test; due to the longer use time, more extensive experience has been accumulated. However, as with other methods (other than numerical methods), there are some disadvantages. First, for a soil layer, if a plurality of undisturbed soil samples taken at different depths are subjected to a compression test, many compression curves are obtained, and it is more difficult to select a representative compression curve in the calculation.
