摘   要：通过调整超缓凝剂掺量（1.0%、1.2%、1.4%、1.6%、1.8%、2.0%、2.2%）、粉煤灰掺量（0、10%、15%、25%）、脱附土掺量（0、20%、40%、60%、80%、100%）、砂率（36%、38%、40%、44%）优选了地铁盖挖逆作法专用混凝土配合比，并对其凝结时间、工作性与力学性能进行了测试，分析了微观形貌与水化机理。结果表明：随着超缓凝剂掺量的增加，混凝土的凝结时间延长，坍落度、扩展度均增加，7 d抗压强度降低，14~56 d抗压强度先增后降；随着粉煤灰掺量的增加，混凝土的抗压强度先增后降；随着脱附土掺量的增加，混凝土的抗压强度降低；随着砂率的提高，混凝土的抗压强度先增后降；配合比最优组合为超缓凝剂掺量1.6%、粉煤灰掺量15%、脱附土掺量40%、砂率40%，以此制备的混凝土具有良好的工作性，较高的早期抗压强度，且后期抗压强度不倒缩；超缓凝剂及矿物掺合料的掺入降低了水泥水化放热温度峰值，延长了水泥的水化进程，且不会影响混凝土后期力学性能发展。Abstract: By adjusting the dosage of super retarders (1.0%, 1.2%, 1.4%, 1.6%, 1.8%, 2.0%, 2.2%), fly ash dosage (0, 10%, 15%, 25%), detachment soil dosage (0, 20%, 40%, 60%, 80%, 100%), and sand ratio (36%, 38%, 40%, 44%), the special concrete mix proportion for subway cover excavation reverse method was optimized. The setting time, workability, and mechanical properties were tested, and the microstructure and hydration mechanism were analyzed. The results show that with the increase of the dosage of super retarder, the setting time of concrete is prolonged, and the slump and expansion increase. The compressive strength decreases at 7 d, and increases first and then decreases at 14~56 d. With the increase of fly ash dosage, the compressive strength of concrete first increases and then decreases. With the increase of detachment soil dosage, the compressive strength of concrete decreases. With the increase of sand ratio, the compressive strength of concrete first increases and then decreases. The optimal mix proportion is 1.6% dosage of super retarder, 15% dosage of fly ash, 40% dosage of detachment soil, and 40% of sand ratio. The concrete prepared from this has good workability, high early compressive strength, and no shrinkage in later compressive strength. The addition of super retarders and mineral admixtures reduces the peak heat release temperature of cement hydration, prolongs the hydration process of cement, and does not affect the later mechanical performance development of concrete.

摘   要：依托某深大基坑工程，研究了混凝土支撑双向伺服调控系统的变形控制效果，分析了基坑的围护结构位移、支撑的轴力及变形、围檩脱开量的变化情况，并利用Midas软件建立了有限元模型进行了数值模拟与验证。结果表明：双向伺服调控系统能有效控制基坑两侧围护结构的变形发展，适用于敏感环境深大基坑多侧变形控制，且伺服调控系统对加载相应方向的围护及支撑的作用效果更为明显，推广应用前景广阔；建立的数值模型能较好地反映基坑实际施工工况，可为基坑工程施工提供一定的参考。Abstract: Based on a deep and large foundation pit project, the deformation control effect of a two-way servo control system for concrete support was studied. The displacement of the retaining structure of the foundation pit, the axial force and deformation of the support, and the changes in the detachment of the purlin were analyzed. A finite element model was established by using Midas software for numerical simulation and verification. The results show that the two-way servo control system can effectively control the deformation development of the retaining structures on both sides of the foundation pit, and is suitable for multi side deformation control of deep and large foundation pits in sensitive environments. Moreover, the servo control system has a more significant effect on the loading direction of the retaining and supporting structures, and has a broad prospect for promotion and application. The established numerical model can better reflect the actual construction conditions of foundation pits and provide a reference for foundation pit engineering construction.
