摘要：采用煤矸石與生石灰、粉煤灰按照合適配合比制成混合料（即煤矸石二灰混合料），并用該種混合料進行地基換填，經過養護后利用平板載荷試驗，測出了該混合料的p-s曲線、s-lgt曲線，得出了地基承載力特征值及變形模量。研究表明，該混合料的地基承載力很高，變形模量也較高，可用作20層以下建筑的地基換填處理材料。 Abstract：Coal gangue, lime and fly ash are mixed according to appropriate mix proportion. Using the mixture to replace the foundation, and using the plate loading test after the curing, the p-s curve, s-lgt curve of the mixture are tested, and the characteristic value of subgrade bearing capacity and deformation modulus are concluded. The research shows that the subgrade bearing capacity of the mixture is very high and the deformation modulus of the mixture is higher as well, which can be used as the foundation replacement material for the buildings below 20 floors.

摘要：為研究聚丙烯纖維混凝土結構的受力性能，對6根不同摻入量的聚丙烯纖維混凝土梁進行了試驗研究，并利用ANSYS有限元分析軟件對其受力過程進行了非線性數值仿真模擬。研究結果表明：摻入聚丙烯纖維的混凝土梁裂縫寬度較相同條件下未摻入聚丙烯纖維的混凝土梁小，聚丙烯纖維能夠提高混凝土梁的抗裂性能；配置HRB500級鋼筋的聚丙烯纖維混凝土梁在使用階段能夠滿足《混凝土結構設計規范》（GB 50010-2010）裂縫寬度限值的要求；非線性有限元數值模擬結果與試驗結果吻合較好，該方法能夠有效地模擬聚丙烯纖維混凝土梁的受力過程。 Abstract: In order to investigate the mechanical properties of polypropylene fiber reinforced concrete structure, 6 polypropylene fiber reinforced concrete beams which have different dosages of polypropylene fiber are analyzed, and using the finite element analysis software ANSYS, nonlinear numerical simulation for the process of experiment is carried out. The results show that the crack widths of polypropylene fiber concrete beam are smaller than the unincorporated ones, the polypropylene fiber can improve the crack resistance of concrete beams. The polypropylene fiber concrete beams reinforced with HRB500 can meet to the requirements of the crack width limits of "Design Specification of Concrete Structures" (GB 50010-2010) during the using phase. And the nonlinear finite element numerical simulation agrees well with the experimental results, which indicates that this method can effectively simulate the force process of polypropylene fiber reinforced concrete beams.

摘要：通過試驗研究了不同體積摻量的聚丙烯纖維和滌綸纖維水泥混凝土的力學性能。結果表明，在低摻量的情況下，滌綸纖維完全可以取代聚丙烯纖維，而且滌綸纖維混凝土的各項性能均優于素混凝土，其中，以抗劈裂性能的優勢最為突出。在高摻量的情況下，滌綸纖維混凝土的各項性能與聚丙烯纖維混凝土的差距較大，不易取代。 Abstract: The mechanical properties of polypropylene fiber and polyester fiber concrete are studied with different volume dosages by experiment. The result shows that under the condition of low dosages, polyester fiber can completely replace polypropylene fiber, and every performance of the polyester fiber concrete precede to the ones of fiber concrete, especially the splitting property. Under the high dosage condition, there are great performance differences between polyester fiber concrete and polypropylene fiber concrete, and the polyester fiber is difficult to replace the polypropylene fiber.
