The invention provides a method for determining the strength of a waterproof bonding layer paved on a polymer concrete steel bridge deck. The method comprises the following steps: simulating the influence of vertical pressure stress on an interlayer in an actual traffic state by adopting an interlayer 75-degree oblique shear and pull-out test; simulating the influence of variable-speed braking on the interlayer in the actual traffic state by adopting a speed changing method; using the rectangular composite test piece corresponding to the bridge in size for interlayer strength detection, the actual condition can be better simulated, and obtaining a more accurate waterproof bonding layer strength value. 本发明提供一种聚合物混凝土钢桥面铺装防水粘结层的强度确定方法，采用层间75°斜剪与拉拔试验模拟实际通车状态下竖向压应力对层间的影响；采用变换速率的方法模拟实际通车状态下变速刹车对层间的影响；采用与桥梁尺寸相对应的矩形复合试件进行层间强度检测，可更好的模拟实际状况，得到更为精确的防水粘结层强度值。
