Abstract


Soft ground under external loads , settlement generally . Structures built on soft clay settlement deformation the key geotechnical problems . Depending on whether the actual situation for soft ground consolidation settlement theory is perfect and reasonable . On the basis of the existing research , consider the nonlinear characteristics of the soil , study of nonlinear consolidation of soft ground subsidence . This paper studies the work are as follows : (1) Research discusses the soft ground consolidation and settlement , in particular, discusses Research and development status of the one-dimensional nonlinear saturated soil consolidation theory . (2) one-dimensional linear saturated soft soil consolidation settlement analysis , discusses the basic concepts of soil consolidation and saturated soil Terzaghi consolidation theory . Settlement calculation method to explore the soft ground workers . The calculation program is compiled in Matlab platform , and with engineering examples , the consolidation of the pile composite foundation settlement is analyzed and calculated , explore the different geotechnical parameters change , the law of the soft ground consolidation settlement . ( 3 ) analysis and the establishment of a nonlinear universal equation for the saturated soft soil penetration unidirectional consolidation , considering stress history of the one-dimensional nonlinear consolidation of the basic equation . (4) With Matlab software engineering instance , one-dimensional nonlinear consolidation settlement calculation and analysis of the saturated soft soil . Considered loading, soil thickness change over time of one-dimensional consolidation calculation, as well as the foundation for the calculation of the one-dimensional layered soil consolidation , and considering the stress history of one-dimensional consolidation equation solving . Get some actual meaningful conclusions .
