However, in designing the beamless slabs with equivalent frame method, the stress is an average values along the depth of section, which varies with the normal service state. Compared with the results by finite element method, the results gained by equivalent frame method cannot satisfy the requirement under the normal service state. Therefore, the tendons of beamless slabs should be designed and arranged based on the results of FEM taking account into vertical load and prestressed load.

本文通过分析，认为采用等代框架法进行无梁板设计时，其内力是基于截面平均的结果，在正常使用状态与实际受力状态有很大的不同，通过对比等代框架法和有限元计算的正常使用极限状态应力可知，按等代框架法设计的预应力布置并不能保证其正常使用极限状态的要求，据此提出了应根据无梁板在竖向荷载和预应力共同作用下弹性有限元分析结果进行预应力筋布置的建议。

However, such tidal overheight is often ignored in the current regional numerical simulation due to intensive computational requirement. Only the mean sea level is used as the fixed seaward boundary, which may wrongly predict the groundwater table position. Therefore, we aim to determine an equivalent seaward boundary through numerical modeling. The equivalent seaward boundary takes into account the tide-induced overheight effects.

然而，由于潮汐动边界处理的复杂性而导致巨大的计算量，在现有的区域地下水数学模型中，潮汐引起的海平面波动通常被忽略，仅仅以平均海平面高度作为模型的海岸边界条件，其预测出的地下水水位位置与实际情况可能会有一定的误差。
