Paper fiber is an important modified material of cement mortar.In order to analyze the basic law of paper fiber modification of the flattened pervious mortar on the foundation surface of tunnel engineering,a modified pervious mortar was prepared by adding paper fiber to the mortar according to different contents,and its volume density,water absorption and compressive strength were analyzed.The results show that compared with the general mortar,the paper fiber modified permeable mortar applied in the initial tunnel support foundation leveling construction is limited in volume density improvement,but has significant advantages in water permeability,compressive strength,etc.,it is a more ideal tunnel support foundation leveling permeable mortar.
