proposed a simple formula for predicting the shear strength of soils under arbitrary consolidation. Therefore, the influence of vacuum-surcharge preloading on the physical and mechanical indexes of foundation soil, the mechanical characteristics of the cast-in-place pile, and the settlement reserve control method of intersecting buildings in soft soil beach area are discussed. The vacuum-surcharge preloading method combined with the cast-in-place pile reinforcement method has been widely considered because of the large increase in foundation bearing capacity and the small settlement after construction. In addition, there are many reinforcement methods for soft soil foundations. However, the coastal geological conditions are mainly thick silty soft soil, and there are many foundation reinforcement problems in reclamation projects. IntroductionĬoastal reclamation has become an effective way to expand urban residential and construction land because of the rapid economic development, population growth, and population density in coastal areas. This paper provides a theoretical basis for the prediction of pile bearing capacity in the preliminary design stage and the evaluation and calculation of differential settlement of intersecting buildings in soft soil beach areas. The research results show that the bearing capacity of a single pile increases greatly with the consolidation of soil around the pile and that the gap width between the structures in the project decreases with increasing consolidation. On this basis, a three-dimensional numerical analysis model of drainage sluice, seawall, cofferdam, and foundation soil is established, and the relationship between the degree of soil consolidation and the development of structural gaps caused by differential settlement is obtained. The change rules for the vertical and horizontal ultimate bearing capacities of a single pile with the degree of soil consolidation are studied.

Then, an interaction model for soft soil and pile soil is established using the geotechnical finite element analysis software MIDAS/GTS NX. First, the change rules for the shear strength and compression modulus of soft soil under different consolidation degrees are studied by theoretical analysis. This paper addresses the problem of open gaps caused by differential settlement in the process of constructing sluice buildings in soft soil beach areas, combined with the construction of sluice and supporting facilities in a reclamation project.
