Therefore, increase concrete anti - pull to stretch ability and reduce concrete control is very necessary. base on above reason, for research of measure of anti - crack of mass concrete in not carry have very of important meaning
為了提高混凝土的抗拉伸能力和減少混凝土的內、外部約束，研究大體積混凝土在非荷載應力作用下的施工系統控制具有十分的重要意義。 -
So he set his ear to the crack and listened, and listened, and listened, and the steps a - scraping around out there all the time ; and at last he nudged us, and we slid out, and stooped down, not breathing, and not making the least noise, and slipped stealthy towards the fence in injun file, and got to it all right, and me and jim over it ; but tom s britches catched fast on a splinter on the top rail, and then he hear the steps coming, so he had to pull loose, which snapped the splinter and made a noise ; and as he dropped in our tracks and started somebody sings out
隨后他把耳朵貼在門縫上，聽啊，聽啊，聽啊，可是四下里一直有腳步聲。到最後，他用胳膊后捅了捅我們，我們便溜了出來，弓著腰，屏住了呼吸，不發任何一點點兒聲音，一跟著一個，輕手輕腳，朝柵欄走去，平平安安地走到了柵欄邊，我和傑姆跨過了柵欄，可是湯姆的褲子給柵欄頂上一根橫木裂開的木片給絆住了，他聽到腳步聲在走攏來，他使勁扯，啪地一聲把木片扯斷了。他跟在我們後面跑。 -
At the same time, the energy absorbed in the crack propagation phase decreases relatively that lead to overall energy absorption of the composites increases slightly, it is greater than 12. 89 %. by observing the appearance of the damage area, it can be found that the mode of damage is influenced by the interfacial shear strength. if the interfacial shear strength is low, fiber pull - out is the primary energy - absorbing mechanisms, whereas the dominant energy - absorbing mechanisms changes into fiber / matrix debonding and delamination when the interfacial shear strength is stronger
界面剪切強度增加后，材料的沖擊極限載荷有所增加，在裂紋起始區吸收的引發能增加較多，其中增強纖維經等離子體處理6分鐘的試樣所吸收的引發能增加了18 . 57 % ;由於裂紋擴展階段所吸收的能量相對有所下降，材料總的能量吸收能力雖有所改善，但增加不多，其中界面剪切強度增加最多的試樣，吸收的總能量增加了12 . 89 % 。 -
Experiment and theories analysis express low shear walls the general occurrence shear to slice the breakage, before shearwalls " concrete crack, the wall plate concrete under takes the big part shear stress, exsist inclined pull lord should dint ; after wall concrete crack, wall plate the reinforcing bar undertakes the big part shear stress, so changes to suffer the mechanism originally, hence formation the inclined direction suffers to press the piece of with suffer to pull the reinforcing bar pull, press the resistance
試驗及理論分析表明低矮剪力墻一般發生剪切破壞，在墻體混凝土開裂前，墻板混凝土承擔大部分剪力，存在著斜拉主應力；在墻體混凝土開裂后，墻板中鋼筋承擔大部分剪力，從而改變了原來的受力機理，於是形成斜向受壓構件（裂縫間混凝土斜壓柱體）和鋼筋的拉、壓抗力。
