Under the condition of high load, the pore water pressure model of building foundation in coastal shallow water area is analyzed, and the experimental loading analysis and mathematical simulation of pore water pressure variation are carried out to overcome the problems of elastic-plastic hysteretic force and discrete distribution of pore water pressure, so as to improve the life of building foundation in coastal shallow water. The load loading of building objects in coastal shallow waters is carried out by means of mechanical anchoring. The constitutive relationship model between elastic modulus, residual strain force and pore water pressure of coastal shallow water building foundation under load loading is analyzed. The pore water pressure variation of strengthened specimens and contrast specimens is measured by numerical test, and dynamic curvature correction is carried out by hysteretic curve recovery dynamic evaluation method. The stress state increment of pore water pressure of building foundation in shallow waters along the coast is obtained. The load and displacement curves of buildings in coastal shallow waters are analyzed by experiments, and the stress cloud diagram of external preelastic-plastic hysteretic force on the foundation of buildings in coastal shallow waters is obtained. The test results show that the numerical simulation of pore water pressure on the foundation of buildings in coastal shallow waters is accurate and reliable, and it has good application value in foundation construction and specimen loading of buildings in coastal shallow waters.
