Discussion on Two Types of Calculation Problems for Shallow Foundation and Vibroflotation Compaction Foundation Treatment
This paper aims to deduce calculation formulas to solve two common geotechnical engineering prob-lems:①Design of foundation size and burial depth adjustment after load change of shallow foundation;②De-sign and calculation of vibroflotation compaction foundation treatment with filler under different conditions.Prob-lem 1:The derivation of calculation formula is to modify the calculation principle formula of depth and width of foundation bearing capacity,and deduce the general simplified formula of foundation condition adjustment after shallow foundation load changes;problem 2:vibroflotation compaction foundation treatment is solved by using the conservation of solid particles.According to this basic principle and the calculation formula of replacement rate,the general formula of target filler volume is derived by changing parameters.The target design parameters can be calculated quickly and accurately by deducing the conclusive formula,and the rationality of the conclu-sive formula can also be proved by examples in this paper.Therefore,it is convenient for technicians to quickly and accurately solve such problems and obtain target design parameters,thus achieving the goal of comprehen-sive evaluation and optimization of design schemes.
