7.2.8.4 The “snug tight” tension shall be approximately 15 percent of the specified tension and
shall be achieved using a calibrated wrench.
7.2.8.5 The sequence of bolt tensioning shall be shown on the drawings.
7.2.8.6 After the snug tight condition is achieved, an initial tension of 75 percent of the final
tension shall be developed in all the bolts. Only then shall the final tension be developed.
7.2.8.7 The final tension shall be verified by testing 10 percent of the bolts after all the bolts are
tensioned. If the verification indicates loss of tension in some bolts, the Contractor shall notify
Engineer. The Engineer and the Contractor will develop the appropriate action.
7.2.8.8 The flange contact bearing surfaces shall have at least 75% of the bearing cross-sectional
area in contact. The outer surface of the flanges shall fit within 0.010 in. (0.25 mm) for 75% of the
length of the edge and not more than 1/32 in. (1 mm) for the remaining 25% of the length.
7.2.8.9 Bolt tension may be verified at locations selected by the Engineer. Bolt tension
verification shall be performed by the Contractor in the presence of the Engineer and in such a
manner that the Engineer can read the torque wrench gage during verification.

应达成以校准过的痛苦。
7.2.8.5预应力锚杆的序列对图纸上应注明。
7.2.8.6紧条件后,实现了舒适的初始张力75%的决赛
建立在所有张力的螺栓。只有那时最后的张力得到发展。
7.2.8.7核定的最终张力测试有百分之十的螺栓在所有的螺栓
刀柄上。如果验证表明损失的张力在一些螺栓时,承包商应通知
工程师。工程师和承包商将开发出相应的措施。
7.2.8.8法兰接触轴承表面须具有至少75%的轴承横截面
在接触面积。法兰的外表面应符合0.010。(0.25毫米)为75%的
边长度,而不是1 / 32。(1毫米)的剩余25%的长度。
7.2.8.9张力可以验证了螺栓的地点选的工程师。螺栓张力
验证承包商均应执行的面在工程师,在这样的一个
