METHOD FOR IMPROVING ANTI-SLIDING AND ANTI-OVERTURNING SAFETY OF EXISTING BALANCED-WEIGHT RETAINING WALL

摘要

Disclosed is a method for improving the anti-sliding and anti-overturning safety of an existing balanced-weight retaining wall. Part of the bearing capacity still reserved by an existing balanced-weight retaining wall is fully taken into consideration, and after anchoring piles are used in front of the existing balanced-weight retaining wall for reinforcement, the resistance of the existing retaining wall is improved, such that the anti-sliding and anti-overturning safety of the structure is improved; and the size of the anchoring piles is designed according to the stress of the existing balanced-weight retaining wall and the stress of the newly built anchoring pile. Compared with the prior art, the load shared by the anchoring piles is reduced, the size of the anchoring piles is optimized, and therefore on the premise that safety is guaranteed, project investment is reduced, and the economical efficiency is improved. Moreover, the anchoring piles and the balanced-weight retaining wall are anchored together by means of steel bars to form a whole, and the structural integrity and the anti-seismic performance are good.
