NUMERICAL ANALYSIS OF THE SHORINGS OF DEEP FOUNDATION PITS WITH REGARD FOR THE SOIL SOLIDIFICATION

摘要

We present a procedure for the evaluation of the rational volumes of soil solidification in the shorings of deep foundation pits higher and lower than the bottom of the pit with an aim to decrease the horizontal pressure of soil upon the shoring and to enhance the resistance of soil to the horizontal displacements of the restraining structure. The problem is solved by using a two-stage iterative scheme with regard for the condition of minimal volume of solidification, which guarantees the variations of displacements at the top of the restraining structure within the admissible limits.
