Abstract

According to different geological conditions and different soft foundation thicknesses, this paper uses Terzaghi's one-dimensional consolidation theory, finite element simulation condition calculation and combined with code requirements to analyze the effects of replacement, cement mixing piles, and prestressed pipe piles on the foundation treatment of silty silty clay, and finally through the comparison and selection of plans, from the perspective of economic and technical rationality, determines the specific treatment method used.


Keywords
