To study the mechanical response relationship between the overall tension of geocell and the tension of geocell strips and nodes， the biaxial tensile test was used to measure the maximum breaking tension of high-strength geocell with different heights and different cell welding pitches when they were tested at different loading velocity. The design reference value of geocell tension was given by using the matching relationship between node strength and strip tension. The response law of the biaxial tension and deformation of the geocell to various influencing factors was studied by the response surface multi-factor test analysis method. The results show that the failures of the high-strength geocell in the biaxial tensile test all occur at the nodes， and the actual engineering design should be paid attention. The degree of influence of the three factors on the overall strength of the geocell is geocell height>geocell weld pitch>loading velocity， the research results can provide a theoretical basis for the technical index selection of the geocell in engineering design.
