| 英文摘要: |
| The research focuses on the development of high-strength geocell technology, with an in-depthanalysis of the tensile properties of geocells, providing a theoretical basis for solving problems related to soft founda-tion reinforcement in engineering and the development of new materials. Through theoretical analysis and experi-mental research, the study investigates the characteristics, raw materials, and manufacturing processes of high-strength geocells. The research includes indoor tensile tests and numerical simulations to study the stress and defor-mation patterns of high-strength geocells. By examining traditional manufacturing processes and incorporating newtechnologies such as special ultrasonic welding, intelligent fiber optics, and fixed locking plates, high-strength geo-cells are developed. Tensile tests are conducted to establish the relationship between elongation, stress, and time.FLAC3D numerical simulations are used to study the mechanical properties of the new geocells, analyzing theirstress-strain relationships and the relationship between time and displacement. Based on the simulation results,guidance is provided for the safe design and construction management of high-strength geocells. |
