以重力式方块码头港池浚深升级改造为例，通过采用截面法，将板桩和重力式结构的协同作用有效地联系起来。板桩结构内力采用竖向弹性地基梁法计算，重力式结构直接采用现行《重力式码头设计与施工规范》中规定的方法进行计算。通过两种结构的联合迭代计算，得出板桩内力和重力式结构抗倾抗滑稳定性及基床顶面应力。
以重力式方塊碼頭港池浚深升級改造為例，通過採用截麵法，將闆樁和重力式結構的協同作用有效地聯繫起來。闆樁結構內力採用豎嚮彈性地基樑法計算，重力式結構直接採用現行《重力式碼頭設計與施工規範》中規定的方法進行計算。通過兩種結構的聯閤迭代計算，得齣闆樁內力和重力式結構抗傾抗滑穩定性及基床頂麵應力。

Taking such a upgrading and reconstruction project that the sheet pile is used in front of original gravity block quay because of deeper basin excavation as an example, we effectively established the interactions between the sheet pile and gravity structure by using the method of sections. The internal force of sheet pile structure is calculated using the method of vertical elastic foundation beam, the calculation of gravity structure is directly carried out based on Design and Construction Code for Gravity Quay. The internal force of sheet pile structure and stability against sliding and overturning and stress on the surface of rock foundation of gravity structure can be obtained through combined iterative calculation of these two different structures.
