Synergetic Mode for Grassland Ecological Management and Animal Husbandry Development in Northern Tibet

Hasbagan Ganjurjav, Hu Guozheng, Gao Qingzhu, Jiangcun Wangzha, Danjiu Luobu,Can Muyou, Basang Wangdui, Yang Fuyu, Wei Xuehong, Yang Yongping

Strategic Study of CAE 2019, Volume 21, Issue 5,   Pages 93-98 doi: 10.15302/J-SSCAE-2019.05.013

Abstract:

Northern Tibet Plateau is an important ecological security shelter for China and a base of animal husbandry with plateau characteristics. However, grassland degradation is threatening the functioning of alpine grasslands and brings great challenges to ecological protection and animal husbandry development. In this study, we analyzed the current situation of ecological protection and animal husbandry development in the Northern Tibet Plateau, summarized the factors affecting the functions of alpine grasslands in this region, and introduced a synergistic mode for grassland ecological protection and animal husbandry development. A series of measures were also proposed to enhance the ecological functions of the alpine grasslands and upgrade the grassland-based animal husbandry, including ecological restoration of degraded grasslands, optimizing grazing management, artificial forage cultivation, developing a“low grass and high grazing” mode (i.e., planting grass in farming areas of low altitude and raising livestock in pastoral areas of high altitude), and half barn-feeding in winter. This study is hoped to provide scientific and technological support in ensuring national ecological security and increasing income of herdsmen.

Seismic effects on reinforcement load and lateral deformation of geosynthetic-reinforced soil walls

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 4,   Pages 1001-1015 doi: 10.1007/s11709-021-0734-8

Abstract: Current design methods for the internal stability of geosynthetic-reinforced soil (GRS) walls postulate seismic forces as inertial forces, leading to pseudo-static analyses based on active earth pressure theory, which yields unconservative reinforcement loads required for seismic stability. Most seismic analyses are limited to the determination of maximum reinforcement strength. This study aimed to calculate the distribution of the reinforcement load and connection strength required for each layer of the seismic GRS wall. Using the top-down procedure involves all of the possible failure surfaces for the seismic analyses of the GRS wall and then obtains the reinforcement load distribution for the limit state. The distributions are used to determine the required connection strength and to approximately assess the facing lateral deformation. For sufficient pullout resistance to be provided by each reinforcement, the maximum required tensile resistance is identical to the results based on the Mononobe–Okabe method. However, short reinforcement results in greater tensile resistances in the mid and lower layers as evinced by compound failure frequently occurring in GRS walls during an earthquake. Parametric studies involving backfill friction angle, reinforcement length, vertical seismic acceleration, and secondary reinforcement are conducted to investigate seismic impacts on the stability and lateral deformation of GRS walls.

Higher-order mode effects on the seismic performance of tall piers

Zhongguo GUAN, Jianzhong LI, Yan XU, Hao LU

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 4,   Pages 496-502 doi: 10.1007/s11709-011-0131-9

Abstract: A comprehensive analysis was conducted to investigate the seismic performance of a typical tall bridge pier through incremental dynamical analysis (IDA). The effect of higher-order modes was studied specifically. The results showed that higher-order modes significantly contributed to the structural seismic response and should not be neglected. Including these modes resulted in an additional hinge midway up the pier. No plastic hinge would occur at this location for conventional bridge piers. Higher-order modes also led to an out-of-phase response between the hinge rotation at the pier bottom and the displacement at the top. This means that the displacement-based seismic design method cannot correctly predict the mechanical state of the critical hinge and therefore is not suitable for use in the seismic design of tall piers. Mistakenly using the displacement-based seismic design method for tall piers may result in a seriously unsafe condition.
