section method
j Iemranfa截面法(seetion method)把闸底板单宽截条的墩上荷载和地基反力等作为底板荷载，用静力平衡方程，计算水闸平底板截面内力的方法，又称荷载组合法。它与倒置梁法一样，近似地取横向(垂直水流向)单宽截条进行计算。 此外，截面法还假定:①地基反力纵向为直线分布，横向为均匀分布(见倒置梁法)。②不考虑闸墩对底板的约柬作用，把闸墩(包括上部结构)的自重作为底板的荷载。此外，作用在底板上的荷载还有底板的自重、地基反力、底板上的水吸、扬压力和截条两侧的剪力(或剪力差)。③截条两侧剪力之差(或向量和)与作用于截条的其它荷载维持平衡.称为不平衡剪力。它在闸墩与底板之间的分配按倒置T形梁的剪应力分布图按比例分配计算，称为剪力(不平衡剪力)分配法。④不考虑边荷载的影响。┌─┬─┬─┬─┬─┬─┬─┬─┬─┬─┬─┬─┬─┬─┬─┬─┬─┬─┐│ │} │口│口│口│口│口│口│ │ │口│口│口│日│口│口│口│土│├─┴─┴─┴─┴─┴─┴─┴─┴─┴─┴─┴─┴─┴─┴─┴─┴─┴─┤│闸墩位置闸墩位置.闸墩位置 │└───────────────────────────────────┘ 故面法内力计算简图 根据上述假定，其计算简图中均布荷载强度q为: q一一q飞一口2牛q3+q、+么q式中qJ、qZ、q3、q;、△俘分别为底板截条单位长度上的自嗽、水重、扬压力、地荃反力和底板所分担的不平衡剪力.q以向上为正戈为包括闸墩所分担的不平衡剪力在内的墩底荷载，图中夕一l，2，3，以向下为正。在N.、、q的作用下，根据静力平衡方程，可以直接求得截条上任一截面的内力(力矩、切力)。截面法不考虑边荷影响，假定地葵反力均匀分布等所引起的误差与倒假梁法是相同的
