| 1 | Model test and numerical simulation on the dynamic stability of the bedding rock slope under frequent microseisms显示文摘Shake table testing was performed to investigate the dynamic stability of a mid-dip bedding rock slope under frequent earthquakes. Then, numerical modelling was established to further study the slope dynamic stability under purely microseisms and the influence of five factors, including seismic amplitude, slope height, slope angle, strata inclination and strata thickness, were considered. The experimental results show that the natural frequency of the slope decreases and damping ratio increases as the earthquake loading times increase. The dynamic strength reduction method is adopted for the stability evaluation of the bedding rock slope in numerical simulation, and the slope stability decreases with the increase of seismic amplitude, increase of slope height, reduction of strata thickness and increase of slope angle. The failure mode of a mid-dip bedding rock slope in the shaking table test is integral slipping along the bedding surface with dipping tensile cracks at the slope rear edge going through the bedding surfaces. In the numerical simulation, the long-term stability of a mid-dip bedding slope is worst under frequent microseisms and the slope is at risk of integral sliding instability, whereas the slope rock mass is more broken than shown in the shaking table test. The research results are of practical significance to better understand the formation mechanism of reservoir landslides and prevent future landslide disasters. | Deng Zhiyun Liu Xinrong Liu Yongquan Liu Shulin Han Yafeng Liu Jinhui Tu Yiliang | 2020 | Earthquake Engineering and Engineering Vibration2020，19，4： | 3 |
| 2 | Fluorescence detection of phosphate in an aqueous environment by an aluminum-based metal-organic framework with amido functionalized ligands显示文摘The on-site monitoring of phosphate is important for environmental management.Conventional phosphate detection methods are not appropriate to on-site monitoring owing to the use of complicated detection procedures,and the consequent high cost and maintenance requirements of the detection apparatus.Here,a highly sensitive fluorescence-based method for phosphate detection with a wide detection range was developed based on a luminescent aluminum-based metal-organic framework(Al-MOF).The Al-MOF was prepared by introducing amine functional groups to conventional MIL to enhance phosphate binding,and exhibited excellent fluorescence properties that originated from the ligand-to-metal charge transfer(LMCT).The detection limit was as low as 3.25µmol/L(0.10 mg/L)and the detection range was as wide as 3–350µmol/L(0.10–10.85 mg/L).Moreover,Al-MOF displayed specific recognition toward phosphate over most anions and metal cations,even for a high concentration of the co-existent ions.The mechanism of phosphate detection was analyzed through the characterization of the combination of Al-MOF and phosphate,and the results indicated the high affinity between Al-O and phosphate inhibited that the LMCT process and recovered the intrinsic fluorescence of NH2−H2BDC.The recovery of the developed detection method reached a satisfactory range of 85.1%–111.0%,and the feasibility of on-site phosphate detection was verified using a prototype sensor for tap water and lake water samples.It was demonstrated that the prepared Al-MOF is highly promising for on-site detection of phosphate in an aqueous environment. | Peng Li Lingqian Dong Han Jin Jingren Yang Yonghui Tu Chao Wang Yiliang He | 2022 | Frontiers of Environmental Science & Engineering2022，16，12： | 0 |
