Abstract：
During penetration through the backfilled stratum, bored pile construction often faces many problems, such as bigger construction difficulty, longer construction period and higher construction cost, so it's very important to choose a proper backfilled stratum treatment method. Based on practical experiences, analysis and comparison are made among application scope, advantages and disadvantages of slurry wall protection method, cylinder wall protection method, secondary backfilling method and special drill method.
