Abstract

The invention discloses a method for calculating the height of pre-pressed soil based on actually measured sedimentation data. The method is established over calculation of foundation average concreting degree through a Gaomujunjie method. Various parameters are obtained by calculating the actually measured sedimentation data. The method comprises the following steps of: firstly, calculating the foundation concreting degree under an instantaneous loading condition through the actually measured sedimentation data; then, calculating concreting coefficients by operating a least square method through the foundation concreting degree under the instantaneous loading condition; and finally, calculating the pre-pressed height by calculating the foundation average concreting degree according to the Gaomujunjie method. Compared with the traditional method for determining pre-pressed height, the method disclosed by the invention has the advantages that: various calculation parameters are obtained through the actually measured sedimentation data and closer to engineering practice; the method is capable of calculating the height of the pre-pressed soil in the section according to various observation section sedimentation data so that the method has strong pertinence; simultaneously, programming calculation of software, such as MATLAB and the like, can be carried out; and the data is simpleand convenient to process and convenient to popularize and apply.

Description

technical field

[0001] The invention relates to a method for calculating the height of pre-compacted soil based on actually measured settlement data. Background technique

[0002] At present, the determination of preload height and preload time is mostly based on indoor experiments. Because the soil parameters obtained from the test are quite different from the actual ones, there is a relatively large deviation between the calculated results and the actual engineering. Therefore, making full use of the field measured data to determine a reasonable calculation method for the preload height of embankments on soft soil foundations is of great significance for rationally arranging the construction period and ensuring the quality of the project. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a method for calculating the height of pre-compacted soil based on measured settlement data, which is close to engineering pra...
