ANALYSIS OF OPTIMIZEING BRED HOLE PILE-RAFT FOUNDATION TO COMPOSITE FOUNDATION OF THE RIGID PILE
Under the complex geological conditions,the construction of the bored cast-in-place pile is difficult to form piles,which slows down the construction period and greatly increases the construction cost.Based on this,combined with the use of CFG pile composite foundation in high-rise buildings and the geological formation conditions of the site,consider the drilling pile-in-raft foundation,using rigid pile composite foundation to meet the bearing capacity requirements,ensure the structural safety,speed up the construction period and reduce the construction cost.The rigid pile composite foundation for the construction process is long reinforced concrete pile+long plain concrete pile,the long and short pile are staggered,the pile top is laid with the appropriate thickness of graded gravel cushion,and the foundation raft is constructed in the upper part of the cushion layer.
