This research wants to understand for slag additament to restrain of ocean-sand concrete shall be getting worse. To separate river-sand and ocean-sand made fine aggregate, by means of slag additament be able to substitute for cement 20%~40%, and be able to set W/C=0.385、0.485 and 0.585 to make compressive、tensile and bending motor test sample, and shall be curing 3、7、28 and 56 days to search for relation of slag be able to substitute for cement、W/C、curing time and strength.

本研究为了解炉石抑制海砂混凝土材料恶化之效应，乃分别以河砂及海砂做为细骨材，以炉石替代水泥量，分别为20%~80%，并设定水灰比为0.385、0.485及0.585制作抗压、抗拉及抗弯水泥砂浆试体，并养治3天、7天、28天及56天探讨其炉石替代量、水灰比、养治龄期与强度间的关系。

This research shall be obtain that ocean-sand motor shall have more compressive strength early, but later strength shall descend, by means of non-standard sand mixing sample is quite obvious. By means of 50% ocean-sand substitutes for river-sand to mix fine aggregate compressive strength early shall be risen 20%~30%; Adds slag to ocean-sand or a half of river-sand and ocean-sand to make motor test sample, Compressive strength、bending strength and tensile strength shall be according to slag additament, by means of. slag add itament substitutes for cement 40%~60% is most. But slag be able to substitute for cement is too enough, 1ater strength shall be descent.

由本研究可得知海砂拌和的水泥砂浆，其早期抗压强度较高，而晚期强度则有下降的趋势，其中以非标准砂拌和效果最为明显；若以50%海砂替代河砂做为拌和细骨材，其早期抗压强度约上升20%~30%；添加炉石於海砂或河砂、海砂各半的水泥砂浆，其抗压、抗弯及抗拉强度，会随著炉石添加量增加而增加，其中以40%~60%炉石替代量为最佳，但是炉石替代量过高，晚期强度会下降；在相同水灰比状况下以海砂拌和水泥砂浆做比较，以非标准砂拌和有较高的抗压强度，其强度约比标准砂高10%左右。

The stress distribution of adhesively-bonded metal/metal single lap joints under tensile shear loading is analysed using elastic-plastic finite element method .The influence of lap length on the strength of adhesively bonded metal joints which are bonded with phenolic resin and acrylic resin respectively is discussed in detail. It is shown that adhesive has great influence on the stress distribution of the lap region. With the increment of lap length, the stress concentration of adhesive layer decreases.

本文在对国内外关于金属-胶层复合材料接头力学性能数值研究及发展现状进行综述的基础上，运用有限元法并结合实验手段主要研究了胶接接头承载后的力学行为，综合考虑了几何尺寸和物性参数对接头强度和应力分布的影响，并运用层次分析法对胶接质量进行综合评估，综合考虑接头形式，制造工艺，操作人员素质等因素的影响。

To ensure close adhibition of connecting board, screwing should start from center to outside, that is, screwing from enlarged center to skirting area. To avoid coating's influence on tensile force, screwing work should be finished on one day. And to decrease prestress' difference of high-tension bolt, bolt screwing runs in two steps: primary screwing and final screwing. For large-scale joint with great amount of bolts demands a second screwing.

为使被连接板叠密贴紧，应从螺栓群中央顺序向外施拧，即从节点中刚变大的中央按顺序向下受约束的边缘施拧，为防止高强度螺栓连接副的表面处理涂层发生变化影响拉力，应在当天终拧完毕，为减少先拧后拧的高强度螺栓预拉力的差别，其拧紧必须分为初拧和终拧两步进行，对于大型节点，螺栓数量较多，则需要增加一道复拧工序。
