  • Analysis of the relationship between food production, water resources and power consumption in North China

    • Authors: Wang, H.; Yang, G.;  Advisor: -;  Participants: - (2017)

  • The article selected the North China Plain, a concentration zone of the Huang-huai-Hai major grain production region, analyzed the relationship between grain production and the consumption of water and power through statistics data. The results show that the development of the irrigation agriculture greatly promoted the increasing of the grain production in the study area; and the groundwater is still dominant water resources in the farmland irrigation although there are the decreasing trend of the total water utilization amount and consumption structure of the increase of surface water consumption. And, the exponential relationships are obvious between groundwater consumption and the...

  • Structural Health Monitoring of Railway Transition Zones Using Satellite Radar Data

    • Authors: Wang, H.;  Advisor: -;  Participants: - (2018)

  • To tackle the limitations of the in situ techniques, a Satellite Synthetic Aperture Radar (InSAR) system is presented in this paper, which provides a potential solution for a consecutive structural health monitoring of transition zones with bi-/tri-weekly data update and mm-level precision. The results show that the differential settlement in the transition zone and the settlement rate can be observed and detected by the InSAR measurements. Moreover, the InSAR results are cross-validated against measurements obtained using a measuring coach and a Digital Image Correlation (DIC) device. The results of the three measuring techniques show a good correlation, which proves the applicabilit...
