The comprehensive evaluation of the site and foundation stability of geotechnical engineering investigation is an important basis for the design and construction of building foundations. Whether it is correct or not reflects the engineering geological conditions and the characteristics of geotechnical engineering, and is related to whether the engineering design and construction are safe and reliable. The measures are appropriate and the economy is reasonable. Aiming at the engineering practice of using compacted fill as the supporting layer of multi-layer civil building foundations in the construction of new rural areas in coastal areas, the engineering mechanics of compacted silt was studied through indoor and in-situ tests of compacted silt Characteristics, the basic physical and mechanical properties of silt as a filling material are analyzed, and the strength and deformation properties of compacted silt and undisturbed silt under different moisture contents are compared. The test results show that the compacted silt with good construction quality control It has better physical and mechanical properties under natural humidity, with higher strength and stiffness, and different moisture content has a greater impact on the strength and deformation characteristics of compacted silt than undisturbed silt, and should be strictly controlled during construction Water content of compacted silt.
