Polymer Curing Agent in Ecological Protection Design Weak Rock Slope Engineering Application

Abstract

The polymer curing agent was used in the slope and the external-soil grass-planting was then carried out. It was found that this new ecological protection technique can effectively prevent, weaken, or slow down the softening of weak rock slope. Its waterproofness, hydrophobicity, and surface structure with good greening effect were thus improved. The effectiveness of polymer curing agent used in the weak rock slope was evaluated and verified by testing its workability, adhesion, waterproofness, and hydrophobicity. The safety factors of slope stability under three conditions, including not setting curing agent layer, setting curing agent layer, and setting curing agent layer with 25% rock bolt reduced, were calculated by using the Slide software version 5.014. They are 1.199, 1.281, and 1.238, respectively. It was indicated that the safety factor of weak rock slope setting polymer curing agent layer was 6.84% higher than that without the setting polymer curing agent layer. Based on the preceding research, the polymer curing agent as a new ecological protection technique was verified and summarized through the practical engineering projects, which could be expected to be applied in the weak rock slope protection engineering.
