During the removing of two post-tensioning PC continuous bridges,their duct grouting is investigated and some prestressed strands are collected.
在两座后张法PC连续梁桥拆除过程中,现场调查得到了该两座桥的预应力孔道压浆情况和预应力钢绞线试样。
For water-uncouple charge,detonation wave shocks and presses water and stimulates shock wave,transmitting blasting pressure to rock through water and so its pressure of bore wall descended;for air-uncouple charge,however,products of detonation swelled and filled whole bore and then effects bore wall and its pressure of bore wall is the smallest among the three condit.
水不耦合装药,爆轰波冲击压缩水介质激起水中冲击波,由水将爆炸压力传递给岩石,孔壁冲击压力降低;而空气不耦合装药,爆轰产物则膨胀充满炮孔后再作用于孔壁,孔壁压力最小。
