Foundation structure of disassembly-free UHPC thin shell in harsh environment and construction method

The invention discloses a foundation structure of a disassembly-free UHPC thin shell in a harsh environment and a construction method. The foundation structure comprises a prefabricated UHPC thin-wall shell with clustered studs, a core area cast-in-place common concrete inner core and a longitudinal and transverse assembly structure arranged at the bottom of the thin-wall shell. The construction method of the disassembly-free ultra-high performance concrete thin-shell foundation comprises the steps that after the UHPC thin-wall shell is prefabricated in a factory, positioning and assembly connection are conducted on site through the longitudinal and transverse assembly structures, and finally a common concrete core area is poured. According to the disassembly-free UHPC thin-shell foundation, the material characteristics of high strength, good ductility, high durability and the like of UHPC are fully played, and meanwhile the advantages of industrialized production, assembly type construction and the like are
