    摘 要:對不同煤矸石摻量下的煤矸石保溫混凝土進行了抗壓、抗拉及保溫性能試驗研究。結果表明,煤矸石的加入不利于混凝土的強度,且隨著摻量的增加,強度逐漸下降;但隨著齡期的增加,不同煤矸石摻量的煤矸石保溫混凝土的立方體抗壓強度呈現一定的上升趨勢;隨著煤矸石摻量的增加,煤矸石混凝土的導熱系數呈下降趨勢,保溫性能逐漸增強。當煤矸石摻量為30%時,C30煤矸石保溫混凝土的強度和保溫性能均滿足使用要求,即煤矸石替代部分粗骨料應用于保溫混凝土是可行的。 Abstract: In different coal gangue, the gangue insulation concrete compressive and tensile test and thermal insulation properties were carried out, the results show that the compressive strength and splitting tensile strength gradually decreased when the coal gangue added to the concrete. With the increasing age, different coal gangue thermal insulation concrete cube compressive strength showed a rising trend. With the increase of the coal gangue content, the thermal conductivity of coal gangue concrete tends to decrease, and the thermal insulation performance is enhanced. The strength and thermal insulation performance of C30 concrete can meet the requirements at the same time, when the coal gangue content was 30%. It is proved that it is feasible to use coal gangue in the field of thermal insulation concrete, instead of coarse aggregate.

    摘 要:為探究后錨固群錨試件在純彎作用下錨板剛性性能的發揮,設計并制作了9個不同錨板厚度與錨栓間距的后錨固試件,主要研究了試件的破壞形態、極限承載力、錨栓應變、錨板應變和位移。結果表明,當錨板厚度大于18mm和錨栓間距小于10倍錨板厚度時,錨板的強度利用率較高,能達到70%左右。錨栓間距的增加或錨板厚度的增加,都會使后錨固試件的極限荷載得到提高,且錨板厚度的影響更為明顯。錨板厚度過小或錨栓間距過大時,錨板應變發展迅速,錨板剛性性能較差。 Abstract: In order to investigate the properties of the rigidity of anchor plate under pure bending, 9 anchor plates with different thickness and anchor arrangement were designed to study the failure mode, ultimate bearing capacity, anchor strain, strain and deformation of anchor plate of specimens. The results show that utilization ratio of anchor plate strength will reached 70%, when the plate thickness more than18mm and anchor distance smaller than 10 times of plate thickness. The increase of the anchor bolt distance or thickness of the anchor plate lead to increasing of the ultimate bearing capacity, and the influence of the anchor plate thickness is more obvious. When the thickness of the anchor plate is too small or the anchor bolt distance is too large, the strain of the anchor plate develops rapidly, and the rigidity of the anchor plate is not excellent.

    摘 要:使用DYS-2500高溫高壓巖石三軸試驗機對含面層再生混凝土圓柱體進行了單軸壓、常規三軸壓縮試驗研究。試驗結果表明,含面層再生混凝土在單軸壓和三軸壓縮下試驗破壞形態有所差別;在圍壓作用下含面層再生混凝土應力-應變關系曲線發展趨勢平緩豐滿,沒有明顯的峰值點;圍壓有助于提高含面層再生混凝土的峰值應變和峰值應力;15MPa圍壓時的峰值應力約為單軸壓下峰值應力4.4~4.7倍,取代率對峰值應力的影響甚微;圍壓15MPa時的峰值應變比圍壓0時的峰值應變增加了7%~13%;取代率對再生混凝土的峰值應變有一定影響,大體呈遞減趨勢,但不明顯。 Abstract: The regenerative concrete cylinder surface uniaxial and conventional triaxial compression test research was carried out by using DYS-2500 high temperature and high pressure rock triaxial testing machine, the test results show that including surface recycled concrete under uniaxial compression and triaxial compression test failure pattern is different. The stress-strain curve under the effect of confining pressure containing recycled concrete surface and develop gentle plump and have no obvious peak point. Confining pressure is helpful to enhancing the surface peak strain of the recycled concrete and the peak stress. When the confining pressure is 15MPa, the peak stress is the 4.4~4.7 times of that under uniaxial pressure. The influence of replacement ratio on peak stress is little. The peak strain of the confining pressure under 15MPa increased by 7%~13% than that under 0. The replacement ratio of recycled concrete has a certain influence on the peak strain, generally showed a trend of decline, but not obvious.

    摘 要:某學校教學樓地處8度抗震設防地區,由于現行抗震規范的變化,使原有建筑物的承載力及抗震構造均不滿足規范要求。為保障該校舍在地震中的安全性,結合校舍結構的特點和加固需求,采用隔震技術對其進行加固處理。本文介紹了該項目的設計要點,并選取7條地震波進行非線性時程分析。計算結果表明,隔震結構的水平向減震系數小于0.4,降低了上部結構所受的地震作用,提高了工程結構的安全性;相關成果對中小學砌體結構校舍抗震加固具有重要參考價值。 Abstract: Due to the change of the current seismic code, the existing bearing capacity and aseismic construction cannot meet the specification requirements for the teaching building with 8-degree of earthquake fortification intensity. To ensure the safety of this teaching building in the earthquake, the characteristics and reinforcement demand of this teaching building structure was analyzed. Combined with the characteristics of school buildings, seismic isolation technique was used to reinforce this teaching building. The key points of the design for this reinforcement project is projected, in which seven seismic waves were selected to conducted nonlinear time-history analysis. The results showed that the earthquake effect on the upper structure was reduced for the horizontal seismic decrease coefficient less than 0.4, and hence the safety of this building structure was improved. The conclusion can provide the reference for seismic strengthening of masonry structure in primary and secondary schools.
