［摘要］對目前整體大面積筏板基礎(chǔ)設(shè)計中實際存在的問題展開論述，主要涉及地基壓縮層計算深度、上部結(jié)構(gòu)荷載重分配、上部結(jié)構(gòu)布置原則、筏板基礎(chǔ)彎矩的影響因素和計算控制條件。同時指出筏板基礎(chǔ)和常規(guī)上部結(jié)構(gòu)在極限狀態(tài)設(shè)計過程中的區(qū)別和應(yīng)重點考慮的因素。

Abstract:The practical problems in the design of the integral large-area raft foundation were discussed, mainly including the influencing factors and control conditions of calculated depth for the compressed layer, the load redistribution of superstructure, principle of arrangement of superstructure, and the influence factors and calculation control conditions of bending moment. At the same time, it pointed out the difference between the basic design of the raft foundation and the conventional superstructure in the ultimate state in the process of designing and the factors that should be emphatically considered.
Keywords:integral raft foundation; depth of compressed layer; load distribution; ultimate state
