DEM Simulation of Biaxial Compression Experiments of Inherently Anisotropic Granular Materials and the Boundary Effects by Zhao-Xia Tong, Lian-Wei Zhang, Min Zhou

“…The results demonstrate that the boundary condition plays a significant role on the stress-strain relationship and strength of granular materials with inherent fabric anisotropy if the stresses are calculated by the force applied on the wall. However, the responses of the particle assembly measured inside the specimens are almost the same with little influence from the boundary conditions. …”

Improved Kalman filter indoor positioning algorithm based on CHAN by Rui JIANG, Yue YU, Youyun XU, Xiaoming WANG, Dapeng LI

“…Due to the raising complexity of the indoor environment, the influence of the non-line-of-sight error is gradually increasing in indoor positioning.How to reduce the non-line-of-sight error in the indoor positioning environment is particularly significant.The UWB indoor positioning technology was selected, Kalman filter has been used widely in reducing the positioning error in indoor non-line-of-sight situations.However, in the process of switching between line of sight and non-line-of-sight scenes, the Kalman filter will produce a new error.To solve this problem, an improved Kalman filter indoor positioning algorithm based on CHAN was proposed.The ranging results of five or more base stations were used to construct a positioning solution equation set.Then the CHAN algorithm that was sensitive to positioning errors under non-line-of-sight conditions was selected to calculate the result.Finally, residual processing was performed with the results of each base station and different confidence regions were judged in line with the residual processing.For different confidence regions, the Kalman filter preset gain factor K was used to improve the stability of the positioning result and reduce the positioning error in the conversion process.In the simulation environment, the error can reach about 80 cm.In real scene, the algorithm can reduce the positioning error in non-line-of-sight scenes to 60 cm, which can improve accuracy 60% higher than normal complex indoor positioning.…”

Construction Technologies of Self-compacting Concrete for Lining of Water Conveyance Shield Tunnel by SHI Aijun, WANG Yongjian, YAO Chukang, XIE Xiangming, WU Yulong, CAI Yixin

“…Some problems exist in the construction of composite lining of water conveyance shield tunnel,such as vertical transportation of self-compacting concrete (SCC) in deep work shafts,long-distance horizontal transportation of SCC in tunnels,and placing and casting of SCC in closed ring structures.In response to them,a transportation method and a placing mode suitable for SCC were chosen.The spacing of casting holes on the lined steel pipe (inner mold) was reasonably determined for SCC through a simulation test.Depending on the characteristics of the composite lining structure and the construction performance of SCC,related calculations and analyses are carried out for reasonable determination of the casting process and quality control measures such as the length of casting section,layer thickness,and placing speed.The determined parameters were applied in the pilot project of Shenzhen main branch of the Water Resources Allocation Project in the Pearl River Delta.We found that no aggregate separation occurred during the transportation of SCC,and the lined steel pipe did not float up or drift sideward during the casting of SCC.The drilling and coring test results showed that the height of the void between SCC and outer lining segment on the vault met the design requirements,and the lining space of closed ring structures was filled after backfilling and grouting.These results indicate that the SCC of composite lining is of good quality.Relevant construction technologies can provide references for the construction of similar projects.…”
