CONSTRUCTION METHOD OF FRONT BLOCK TYPE REINFORCED EARTH RETAINING WALL USING GEOGRID IMPROVING PULL-OUT RESISTANCE

摘要

PURPOSE: A construction method of a front block type reinforced earth retaining wall with improved pull-out resistance using geogrid is provided to prevent bulging by increasing the friction with backfilling soil. CONSTITUTION: A construction method of a front block type reinforced earth retaining wall with improved pull-out resistance using geogrid is as follows. The ground of a construction site is excavated and arranged. Foundation is formed in the arranged ground. Front blocks(10) are built on the top of the foundation. Backfilling aggregate(20) is filled in the rear of the front blocks. Backfilling soil(30) is filled in the rear of the backfilling aggregate. Geogrid(100) is installed on the backfilling soil. Other front blocks are built on the top of the front blocks. Backfilling aggregate is filled in the rear of the front blocks. Backfilling soil is filled in the rear of the backfilling aggregate. Geogrid(100') coupled with a friction plate is connected to the front blocks.
