ABSTRACT

Taking the design of prestressed anchor cable type extra-long and extra-deep retaining wall structure of Guantang Hot Spring Resort Hotel Project in Yanji City, Jilin Province as an example, the geological and hydrological conditions were analyzed, the reliability and applicability of geotechnical parameters and indicators, frost depth and frost swelling, and site stability were evaluated, and recommendations for foundation design and construction were put forward, along with the design method. Through support monitoring and verification, it shows that the selection, support design scheme, and design measures of the slope retaining wall support project are practical and feasible, and meet the requirements of the current technical specification for retaining and protecting building foundation excavations (JGJ-120-2012), and shorten the construction period and reduce the project cost, and provide a reference for the design of similar retaining wall structures.
