Abstract

Research purposes：Taking the railway engineering as an example, the study is done on the bearing capacity of foundation under flexible embankment load for controlling the foundation deformation.

Research conclusions：In the current code, the characteristic sampling value o f subgrade's bearing capacity is determined according to the relative deformation in plate load tes, tresulting in making no full use of the bearing capacity of soil foundation. In order to make full use of the foundations' bearing capacity, the characteristic sampling value of foundation's bearing capacity should be determined according to the various allowable settlement standards for the different projects in the design of railway engineering. Under the premise of meeting the deformation requirements, the characteristic sampling value of foundations' bearing capacity should be appropriately expanded in order to achieve the harmony and unity between the strength and deformation. The conclusions presented in this paper can be as reference to similar railway engineering.

Key words

deformation control / bearing capacity of foundation / flexible embankment / load tes / trail way subgrade
