关于地基最终沉降量的计算方法——分层总和法的几点理解

On the Final Settlement of the Foundation of the Calculation Method——Layerwise Summation Method to Understand the Points

每一种土都具有可压缩性,当然一些土的压缩性非常高,而另一些土的压缩性很低。要确定地表沉降,需要有沉降预测方法。沉降预测方法以土的压缩性为基础。土的压缩随建筑物(荷载大小与性质)和土体的不同而变化。如果地基的压缩性参数和上部荷载的大小与性质已知,压缩量即可求出。如果计算出的压缩量在允许范围之内,就是良好的地基土;如果沉降量偏大,就需要进行处理,以满足基础设计的需要。

In each of the soil compressibility are, of course, some soil is very high compression, while others have very low compressibility of the soil. To determine the need for settlement of ground surfaee settlement prediction method. Approach to settlement prediction of soil-based compression. The compressed soil with the Building （the size and nature of load） and soil vary. If the foundation of the compression parameters and the upper part of the size and nature of load is known, can be obtained compression. If the calculated amount of compression within the scope of the permit, that is the foundation of good soil; if large settlement on the need for treatment, designed to meet the needs of the foundation.
