Method for building one-dimensional cumulates in two-storied foundation load in two stages

Abstract

This is a kind of founding method for the two grade adding load double floor groundwork planar solidifying body. It's a kind of solidifying method directly used in the field of civil engineering. Its building method is as follows: build equivalent relation of grading adding load double floor groundwork planar solidification; input road embankment designed parameters, that is embankment top, fundus width, embankment height and average bearing weight; input composite groundwork parameters; input down lying floor groundwork parameters; input solidifying control parameters, that is total solidifying time, the calculating point number of solidifying time, the solidifying time value, the solidifying depth point number and the solidifying depth value; have numerical value calculation,; have Laplace transform on the double floor groundwork solidifying problem equation to do value calculation, then have Laplace counter transform to the image function of effective stress by the use of Stevest inversion formula, calculate to get the sedimentation distortion displacement and hole hydraulic pressure value of every depth point, forecast the after-building sedimentation according to the sedimentation distortion of the down lying floor; output the solidifying sedimentation calculating results of every depth point.

Description

Technical field [0001] The invention is a method for controlling deformation design of building structure and road engineering and researching related soft soil foundation consolidation deformation, in particular to a two-stage loaded double-layer foundation one-dimensional consolidation directly applied in the field of civil engineering The establishment of, the use of this technology combined with related geotechnical tests to obtain calculation parameters, and finally calculate the settlement deformation of the soft soil foundation and predict the settlement deformation after construction. Background technique [0002] In the past ten years, China has been carrying out large-scale infrastructure construction, such as the construction of urban high-rise buildings, highways, railways and other key projects. In the process of high-rise buildings, highways, and railways, soft soil foundations are inevitably encountered. There are often many engineering problems in the construction...

Problems solved by technology

[0002] In the past ten years, my country has been carrying out large-scale infrastructure construction, such as the construction of key projects such as urban high-rise buildings, expressways, and railways. During the construction of high-rise buildings, expressways, and railways, it is inevitable to encounter soft soil foundations. Many engineering problems often occur in the repair of high-rise buildings, highways, and railways in soft soil areas. The settlement and deformation after construction are too large, which affects the normal use of the structure; The water system flows smoothly, and there are hidden dangers of flood control and flood figh
