摘要
利用旋喷桩施工过程中的返出浆液 ,形成桩间系梁 ,不仅能减少环境污染 ,同时提高了复合地基的承载力和抵抗变形的能力。分析了桩、土体和梁的共同工作性状 ,建立了系梁的力学分析模型 ,给出了系梁变形和内力表达式。通过工程实例 ,证明了系梁在旋喷桩复合地基中的重要作用 ,这种方法可推广到各种岩土加固工程和建筑工程中。
Utilizing returning concrete liquid to ground,beams between piles are formed in the proccess of composite foundation construction,which can reduce pollution of the environment and improve the bearing capability and resistance to deformability of composite foundation. The interaction of piles,soil and beams is analyzed.A mechanical model is set up for a beam between two piles,and its expressions of the deformation and internal forces are given.An engineering case is studied,and its results have shown that the beams are important in composite foundation.The method can be popularized in all kinds of geotechnical engineering and construction engineering.
