【摘要】 通过变换柱排支护结构中圈梁的尺寸和材料特性，研究了圈梁的特性对基坑支护结构稳定性的影响。研究结果表明，采用合适的圈梁尺寸和材料，可以提高支护结构的稳定性；优化圈梁对桩排的结构性能比，可以取得事半功倍的效果。更多还原

【Abstract】 By Changing the size and material characteristic of circle beam of pile raft support structure,this paper finds that the stability of support structure of deep base-pit is influenced by the characteristic of circle beam. Adopting the suitable characteristic of circle beam, the stability of support structure can be improved, and twice results with half effort can be got if the structural function ratio of circle beam and pile groups is optimized.更多还原
