摘要
桩围复合式地下仓是一种用支护结构与主体结构全面结合的新型地下结构形式,具有施工方便、经济、安全等特点.利用理正深基坑软件建立了支护桩与腰梁共同作用的三维计算模型,对比分析了地下仓直径、基坑开挖深度、桩直径和间距、腰梁间距等因素对结构受力和变形的影响,分析了影响支护桩与腰梁共同作用的因素,为进一步的研究和设计工作提供依据.
The underground pile-enclosed composite bin is a new structure that combines the supporting structure with the main structure. It has the advantages of convenient construction, economy and security. A three dimensional calculation model that took the interaction of supporting pile and waling into account were established by FSPW. Comparative analysis of the influence of the diameter of underground bin, the depth of foundation pits, the diameter and spacing of pile, the spacing of waling on structural stress and deformation had been done, and factors having an impact on the interaction of pile and waling were analyzed. The paper provides the basis for further research and design.
