These loads can be applied by overstretching, when the forces trying to pull a structure apart are greater than the intrinsic strength of the tendon, ligament, muscle, or fascia.

这些负荷也许会来自过度练习，比如尝试过度拉伸肌腱、韧带、肌肉或筋膜（在拉伸中，肌肉更脆弱，因为拉长时，它是放松的）。

The variation of the box girder's stress and strain is discussed according to the results of the different tensioning sequence. And according to the comparison of the simulation results, a reasonable tensioning sequence is given. It will provide reference for the design and construction of similar projects.

Through analyzing the work characteristic and the work mechanism of the interface in this research paper, bonded rebar technique is applied to the bonding treatment of the interface, the reformative method of enlarging sectional areas is proposed, and the work mechanism of the anchor bar in the interface is analyzed. The work mechanism of the reformative method of enlarging sectional areas and the interface mechanical performance have be more systematical analyzed and studied with the finite element numerical simulation method, the structural testing method, and combing project practice. Based on that, the suggestion formula of shear and tension bearing capacity for the old and new concrete is put forward.

Because we have finished goods delivery time, considering the very urgent, we thought the two schemes, one will do half playmaker position of the deck, another is in inside a waist deck, but we stretch more inclined to the first plan, do not affect the trousers don't hurt the child's shape and skin.

因为我们已经完成了大货，考虑到交货时间也非常的紧迫，我们想到了两个方案，一个将前腰一半的位置做橡筋，另一个是在腰部里面装一个拉伸橡筋，但我们更倾向于第一种方案，不影响裤子的形状也不伤害孩子的皮肤。

During the manufacturing process of OFBG-FRP rod, optical fiber Bragg gratings were pultruded in series along with host materials, i.
