【摘要】 将板式基础与桩基础的优点相结合,给出一种新型的板式中型桩复合基础。在计算基础的抗拔承载力时,既考虑基础及板上土重,又计算桩的摩擦力。在线路荷载较大时,基础上拔、下压承载力随着桩的埋深加长而增加,保证能选出适应多回路、特高压铁塔的基础。内力分析部分采用有限元分析方法,给出了刚度矩阵、位移和荷载向量之间的方程。与传统板式基础相比,本方法大幅减少了土石方开挖量和混凝土耗量,是一种环保、经济的基础。更多还原

【Abstract】 Combining the advantages of slab foundation and piles base,a new slab composite with medium-sized piles foundation is presented. When calculating the pull bearing capacity,the foundation and soil weight,and the friction force of piles are all taken into consideration. Dealing with the large line load,the capacity of bearing of pulling and pressing expand with the increasing length of the piles. Its feature ensures the selection of UHV tower foundation which adapts multi-loop. Furthermore,With the finite element method,the section of Internal Force Analysis of the foundation provides a matrix equation which include stiff matrix,displacement and load vectors. Compared with the traditional slab foundation,the amount of earthwork excavation and concrete consumption is significantly reduced,so it is a base for an environmentally friendly and economical.更多还原
