摘要
针对构造板独立基础地基反力的分配情况不明确,设计该种基础较为困难,进行了工程实测,掌握了第一手动态监测数据,确定出地基反力分配比的实测值和该种基础基底压力的空间变化特点及分布规律。测试结果表明,构造底板能承担30%左右的上部载荷,地基反力分配比应根据最不利组合原则选取。确定地基反力分配比范围以后还可以找出上部载荷与基础内力的相关性,从而为构造板独立基础的设计提供了直接参考依据。
Spread foundation with concrete slab is a new kind of foundation, At present, it is frequently used for engineering, but the circs about the proportion of groundwork reaction isn＇t still nailed down, designing the foundation is therefore difficult. After testing, we have mastered a lot of first-hand dynamic data, so the proportion of groundwork reaction, the spatial characteristic and orderliness of the new foundation can be confirmed. As a result, concrete slab can take on about 30% load of upper structure, but we must integrate it with the worst combination principle at the same time. After the proportion of groundwork reaction is confirmed, we can find the pertinence between upper load and internal force of the foundation, which can offer direct reference basis for the design of this kind of new spread foundation with concrete slab.
