  2. A brief introduction is given to the treatment of the zeya dam foundation, principles of seepage control and design of the concrete face rockfill dam of the zeya reservoir. as for the excavation of the sand - gravel zones, except the toe slab and its 1 / 9 bottom width down stream, the alluvial layers are excavated to the micro - weathered rocks, while the other sections remain unexcavated. regarding to the treatment of the fracture zones, concrete filling is used for the toe slabs and semi - permeable materials are used for other section. according to the construction characteristics, a filter is placed in the down stream embankment foot. to improve the integrity of the dam foundation and anti - seepage capability consolidation grouting and curtain grouting are adopted. as a result safety, economic benefit, convenience in construction and good performace are achieved

    簡要論述澤雅水庫面板堆石壩壩基處理和防滲的原則及設計要點.趾板基礎和堆石體各區砂礫石基礎開挖，除趾板與其下游1 / 9底寬范圍以及壩腳挖除沖積層至弱風化（局部微風化）基巖外，其餘部分均予以保留.斷層破碎帶處理，趾板部位採用混凝土塞，其它部位採用半透水料置換，並根據本工程特點在下游壩腳加設了反濾層.為提高壩基的整體性和防滲性能，對趾板進行了固結和帷幕灌漿.達到了安全、經濟、便於施工的目的，運行情況良好，可為面板堆石壩的設計和研究提供參考與借鑒

  5. Epoxy - bonding a carbon - fiber composite plate to the tension face of concrete beam is an effective technique for repair and retrofit of concrete beams. in the first part of this paper, based on the fracture mechanics and the theory of beam, a theoretic model is proposed to analyze the shear stress in the adhesive between carbon - fiber composite and concrete. and then the closure - form solution for the shear stress distribution is drawn

    本文的第一部分基於斷裂力學與梁的基本理論，對碳纖維加固混凝土梁的粘結膠層以及粘結界面的剪應力分佈進行了理論分析，得出了其理論解析解；討論了碳纖維板的粘結長度、粘結厚度和粘結膠層的抗剪模量對界面剪應力分佈的影響。
  6. Klc of j3 is higher than j2 and j1 at different temperatures, and this shows the stronger ability of j3 to resist crack expanding. two probations have been tried to explore the reasons concerning the results above, one of which is by analyzing the compositions of the three pbxs above and shows that the stronger ability of j3 to resist crack expanding is probably mainly due to the use of bonder b2, and another is by using scanning electronic microscope sem to observe the fracture face morphologies of the specimens at different temperatures. the quantitative observations strongly support the laws of klc of pbxs changes with temperature is revealed as follows : a

    測試了三種高聚物粘結炸藥在不同溫度下的平面應變斷裂韌度k _ （ ic ）值，得到了這三種炸藥的平面應變斷裂隨溫度的變化規律： a 、隨著溫度的增加，高聚物粘結炸藥的平面應變斷裂韌度降低； b 、在45以後j2的平面應變斷裂韌度降低最快，在60時已很差，比j1還低，可以認為j2在高溫下的抗裂紋擴展的能力比j1還差； c 、在不同溫度下， j3的平面應變斷裂韌度比j2和j1的均高，表現出相對較強的抗裂紋擴展能力。
