Current code for design of concrete structure (GB50010—2002) is relatively safe in setting down the corbel's height, horizontal longitudinal reinforcing steel bar and stirrup.

现行的钢筋混凝土结构设计规范GB50010—2002对于牛腿高度、水平纵向钢筋和箍筋的确定方法是偏安全的。

The calculation shows that axial and bending tensile safeties are obviously insufficient, so the problem of arranging the longitudinal reinforcing steel bar should be fully considered.

结果表明，南京长江隧道横向平面内的抗拉和抗剪安全度足够，纵向和弯曲情况下的抗剪安全度足够，抗拉可靠度明显不足，设计中应充分考虑纵向配筋问题。
