Embodiment Construction

[0081] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0082] Such as figure 1 As shown, a method for calculating the degree of consolidation of layered foundations includes the following contents and steps:

[0083] (1) Define complete well foundation and non-complete well foundation:

[0084] The case where the drainage shaft does not penetrate the compressed soil layer is called "incomplete well foundation", otherwise it is called "complete well foundation";

[0085] (2) Based on the definition of incomplete well foundation, the compression layer is divided into two layers: shaft layer and underground layer;

[0086] (3) The shaft layer and the downhole layer are layered according to the natural horizon, numbered sequentially from top to bottom (such as figure 2 ). Each layer in the shaft laye...

Abstract

The invention discloses a method for calculating consolidation degree of a stratified foundation. The method starts from settlement calculation and analyzes the mutual relation between the settlementand the total settlement of each layer in the compression layer of the layered foundation. The difference between the actual stress borne by each layer and the ground preloading load is studied, a newdifferential equation does not need to be established, the adoption of a high-depth complex mathematical method is avoided, the calculation of the consolidation degree of the stratified foundation can be completed only by using a general mathematical method and a spreadsheet, the workload is small, and the precision meets the design requirements.

Description

technical field [0001] The invention belongs to the technical field of soft soil foundation reinforcement in geotechnical engineering, and in particular relates to a method for calculating the degree of consolidation of layered foundations. Background technique: [0002] For the calculation of the degree of consolidation of layered foundations, some use the average index method, such as the method suggested by Gray for the degree of consolidation of layered foundations, using the method of weighted average consolidation coefficient; some also use the method of equivalent thickness. After treatment, it is calculated as a single soil layer. This method can simplify the calculation, but it can only calculate the average degree of consolidation of the entire soil layer, and cannot calculate the degree of consolidation of each soil layer, layered settlement, etc., and the accuracy of the results is not ideal. For other methods of calculating the degree of consolidation of layere...
