Analysis Method for the Pouring Stage of Concrete-Filled Steel Tube (CFST) Arch Bridges Considering Time-Varying Heat of Hydration and Elastic Modulus by Mengsheng Yu, Xinyu Yao, Kaizhong Xie, Tianzhi Hao, Xirui Wang

“…In response to this limitation, this paper proposes an analysis method for the injection stage considering the time-varying heat of hydration and elastic modulus of concrete inside the pipe. Firstly, based on the composite index model of the hydration heat and through the reduction of the participating materials, the heat source function of the hydration heat of the arch rib was obtained, and its accuracy was verified by using two test components. …”

Dynamical Modeling and Active Vibration Control Analysis of a Double-Layer Cylindrical Thin Shell with Active Actuators by Yu Wu, Rui Huo

“…Therefore, this article conducts theoretical research on a novel active vibration control method that inserts an active actuator between a double-layer cylindrical shell to achieve better mid low frequency vibration control effects. Firstly, the substructure admittance method is applied to analytically and dynamically model a double-layer cylindrical thin shell structure with active support, and the vibration power flow of the system is theoretically derived to evaluate the vibration reduction effect. …”

Control technology and application of variable-diameter zoned pressure relief for surrounding rock in deep soft rock and large deformation roadway by Fengfeng WU, Haoyuan GU, Peiju YANG, Changyou LIU, Mintao WEI, Yufei JIANG, Ping WANG

“…It redirects concentrated energy from the shoulder and floor corners deeper into the area, achieving precise pressure relief control within the roadway. ② Increasing the length of shallow small-diameter boreholes (L1), the length of deep large-diameter boreholes (L2), and the radius of deep large-diameter boreholes (r) corresponds to increasing pre-peak, post-peak, and post-peak values in the elastic strain energy density curves, demonstrating an overall positive correlation. ③ As the spacing (D) of deep large-diameter boreholes increases, the peak value of elastic strain energy density between holes shows the characteristics of firstly increasing, then decreasing and then stabilizing, and the effect of unloading joint pressure between boreholes is negatively correlated with it, and based on the magnitude of the increase in the peak value of elastic strain energy, the key parameters affecting the effect of unloading are weighted as follows in the order of: L1, L2, r and D. ④ Based on the theoretical analysis and numerical simulation to determine the key parameters of the 21st transportation downhill roadway pressure relief technology reasonable value, roadway implementation of variable-diameter zoned pressure relief technology, the two ribs and the roof and floor deformation were reduced by 58.7%, 23.7%, and 27.4%, respectively, the stability of the roadway has been effectively controlled, confirming the effectiveness of the variable-diameter zoned pressure relief technology.…”
