结构设计总说明识图讲解
结构设计总说明识图讲解三、自然条件：3.1场地的工程地质及地下水条件：各土层的信息及地下水情况确定合理的基坑支护形式；2.基坑开挖过程中查看实际的土层是否与《岩土工程勘察报告》各土层的信息一致，如果不一致与基坑支护单位协商是否调整支护形式；（1）根据水位表信息确定基坑支护形式；（2）根据水位表信息明确降水方式；（3）对于在干湿交替条件下，注意设计对混凝土结构是否有特殊要求。
（《岩土工程勘察报告》应有建议，设计应考虑。
）四、正负零绝对标高结构说明给出中±0.000的绝对标高，核对结构图与建筑图相对标高±0.00相对应的绝对标高是否一致。
七、设计采用的荷载标准值结构说明中给出的设计荷载标准值，作为顶板拆模后楼面堆载的依据。
八、地基基础8.1 根据<工程地质勘察报告>,本工程整体采用天然地基，基底标高在36.00m左右，持力层土质为第四纪冲洪的粉质粘土、粘质粉土3层，局部存在的有机质粘土、有机质重粉质粘土3-2•层在验槽时视钎探情况酌情处理，综合考虑的承载力标准值(ka)为160kPa。
1. 若工程采用天然地基或复合地基，应随时掌握持力最后一步土开挖时基底的土质情况，如果达不到持力层土质要求，应及时与设计单位、勘察单位、建设单位、监理单位共同协商，从新确定开挖深度。
避免二次开挖。
避免施工成本加大及影响施工进度。
2.如果塔吊基础设置在基底标高，可作为地基是否满足塔吊的地基承载力要求的参考，不满足塔基承载力要求时，需对对地基进行处理，确定处理方法。
8.1.1 天然地基基槽开挖至基底标高以上200mm时，应进行普遍钎探，并通知地质勘测、监理、设计等有关单位共同验槽，确定持力层准确无误后方可进行下一道工序。
