摘要/Abstract

摘要：

通过制备可控低强度材料用作施工狭窄区的回填材料，控制水固比、灰水比和粉煤灰掺量参数，研究了其工作性能、力学性能和耐久性能的变化规律。结果表明：流动性与灰水比和水固比成正相关，设计流动度为25 cm、水泥掺量为4.1%~12.9%时，28 d抗压强度为0.19~0.87 MPa，且抗压强度与水泥用量高度正相关；CBR和回弹模量值与抗压强度具有良好的线性关系；最佳设计配比下材料的压缩变形量远低于粉砂土，具有提高机场基坑与管廊的回填狭窄作业面的施工效率和夯实效果的意义。

Abstract:

This paper prepared a controlled low-strength material for backfilling in the narrow area. The variation rules of its working performance， mechanical properties and durability with the water-solid ratio， the gray-water ratio and the content of fly ash were studied. The results showed that the fluidity of CLSM was positively correlated with the ratio of gray-water and water-solid. The compressive strength was between 0.19 and 0.87 MPa at 4.1%~12.9% of the cement content when the design fluidity was 25 cm， highly positively correlated with the cement content. The CBR value and the modulus of resilience have a good linear relationship with the compressive strength. The compression deformation of mix proportion was much lower than that of silty sand， which can improve the construction efficiency and tamping effect at the narrow backfill surface of the airport foundation pit and pipe gallery.

Key words: road engineering, narrow backfill zone, controlled low strength materials, fluidity, strength
