Abstract In order to improve the defects such as easy cracking and poor long-lastingness of the concretepipe, fiber-based concrete has good crack resistance and durability, and the coarse fiber and basalt fiber of polypropylene are selected, and the fiber-free, single-doped basalt fiber and mono-mixed polypropylene are designed The four groups of concrete pipe knots mixed with basalt-polypropylene coarse fibers were compared and analyzed by three-point tests to analyze the cracking damage pattern, load-displacement curve and carrying capacity of the pipe section, and a numerical model of the three-point test of the fiber concrete pipe section was established. The influence of polypropylene coarse fiber and basalt fiber on the destructive form and carrying capacity of the concrete pipe is further explored. The results show that polypropylene coarse fiber can effectively improve the damage form of concrete pipe, improve the anti-cracking performance and carrying capacity of concrete pipe section, and improve the carrying capacity of B2P4 mixed with basalt-polypropylene coarse fiber pipe by 46.26% compared with fiber-free pipe. In addition, the numerical simulation results of each group of pipe sections are consistent with the test results, and the carrying capacity error is controlled within 5%, which shows that the simulation is reasonable. Through testing and numerical simulation, the optimal doping of basalt-polypropylene coarse fibers to improve the anti-cracking performance and carrying capacity of concrete pipe sections is obtained.

Key words： basalt-polypropylene coarse fiber plain concrete pipe three-point test bearing capacity numerical simulation
