摘要
提出了带钢支撑的水泥土搅拌桩-钢筋混凝土灌注桩连拱基坑支护方案,充分利用水泥土搅拌桩耐压、钢筋混凝土灌注桩可受弯的材料特性,通过拱将两者结合起来,在灌注桩的中部设钢支撑。分析了水泥土搅拌桩、钢筋混凝土灌注桩、钢支撑的受力方式,给出计算方法。理论及工程实践证明带钢支撑的水泥土搅拌桩-钢筋混凝土灌注桩连拱基坑支护体系合理、有效和经济。
The arch pit supporting system with soil cement mixed pile-reinforcing concrete pile is introduced. Taking advantages of the pressure concrete pile and flexible reinforcing concrete pile, the system combines the two by putting the steel supporting structure inside the pile to detract the pressure on soil cement mixed pile. The loaded modes of soil cement mixed pile, reinforcing concrete pile and the steel supporting structure are analyzed, and the calculation method is given out. It is proved that the pit supporting system is feasible, effective and economical.
