选取桥梁结构中的典型T梁桥进行荷载横向分布系数计算模式的研究。将梁格法和刚接梁法计算荷载横向分布系数作比较，得出刚接梁法能够作为拓宽T形梁桥荷载横向分布系数的有效计算方法。同时将有无横隔梁的新旧梁桥拓宽前后的荷载横向分布系数作比较，结论为有横隔梁的连接方式对旧桥提载较明显。
選取橋樑結構中的典型T樑橋進行荷載橫嚮分佈繫數計算模式的研究。將樑格法和剛接樑法計算荷載橫嚮分佈繫數作比較，得齣剛接樑法能夠作為拓寬T形樑橋荷載橫嚮分佈繫數的有效計算方法。同時將有無橫隔樑的新舊樑橋拓寬前後的荷載橫嚮分佈繫數作比較，結論為有橫隔樑的連接方式對舊橋提載較明顯。

The article selects the typical T-beam bridge as the objective to study the calculation mode of the widening load transverse distribution coefficient. By comparing the rigid-connected beam method with the beam-grillage method, it is concluded that the transverse distribution coefficient method is more effec-tive. Meanwhile, by comparing the load transverse distribution coefficients before and after the widening of bridge with or without crossbeam connection, it is concluded that the effect of connection method with crossbeam on improving the load bearing capacity of bridge is more obvious.
