Taiyuan Shanxi 030002 China) Abstract:Large-diameter superHong punehing piles and post grouting technology are adopted in Shanxi Theatre.The project has some difficulties such as high precision of pile position plex geological conditions and strict requirements on post grouting.According to the difficulties and design parameters construction technology and equipments of bored piles and post grouting are introduced and construction quality ensuring measures are put forward.Furthermore static load test and low strain dynamic test are done to test the piles quality.Inspection results show that piles quality ean meet requirements and the post grouting teehnology can improve single pile bearing capacity and deerease settlement of the structure.
