This paper compares the field performance of non-vegetated and vegetated three-layer landfill cover systems utilising construction waste but without geomembrane at Shenzhen Xiaping site in humid climates over a monitoring period 54 months. The top layer each system was constructed using coarse-grained completely decomposed granite (CDG). middle bottom layers were compacted with coarse recycled concrete (CRC) fine-grained CDG, respectively. Numerical analyses also carried out. During 54-month...
Understanding the pore water pressure distribution in unsaturated soil is crucial predicting shallow landslides triggered by rainfall, mainly when dealing with different temporal patterns of rainfall intensity. However, hydrological response vegetated slopes, especially three-dimensional (3D) slopes covered shrubs, under remains unclear and requires further investigation. To address this issue, study adopts a novel 3D numerical model for simulating hydraulic interactions between root system...
Climate change has resulted in increasing attention being paid to the effects of temperature and humidity on vegetated soil. However, existing constitutive models rarely investigate thermo-mechanical behaviour, such as accumulation plastic strain under non-isothermal conditions, unsaturated To address this issue, study developed a comprehensive model by adopting state-dependent dilatancy conjugation with loading, memory, bounding surfaces. Moreover, root-induced hardening due pore occupancy...
Extreme rainfall significantly threatens the safety of landfill cover system, especially under humid climates. This study aims to provide design recommendations for a sustainable system consisting low-permeability soil layer underlying two-layer capillary barrier First, numerical back-analysis was conducted verification against series flume model tests. Then, parametric performed investigate effects inclination angle, particle size and thickness on lateral diversion length (DL) three-layer...
Biochar has been used as a sustainable amendment to moderate the risks of climate change plant and soil management. A 3-year field monitoring was conducted at Shenzhen Xiaping landfill evaluate performance three-layer cover using biochar. Coarse-grained completely decomposed granites (CDG) amended with peanut shell biochar 0%, 5% 10% (m 3 /m ) were for top layers three grass plots (10 m×5 m each), respectively. Coarse recycled concrete fine-grained CDG middle bottom all plots. Numerical...
Abstract The adaptive reuse of architectural heritage is the basis embodying its core value, bringing new life to architecture, and an important way integrate it into contemporary development. In many current studies, focuses on research framework most effective method for a certain building. whole process, post evaluation strategy based specific cultural background ignored, buildings dynamic process. Therefore, this study takes 9 sites along central axis Beijing (including three types...
Field monitoring was conducted to investigate and quantify the long-term effects of peanut shell biochar on soil-grass interaction over three years. Three 10 m × 5 grassed plots were constructed in completely decomposed granitic soil. Two them amended, respectively, with 5% 10% contents (m3/m3) for grass growth, while third without amendment. During three-year monitoring, plant characteristics, saturated water permeability (ks) soil suction measured. The monitored results show that leaf area...
Abstract As significant evidence of ice-rich permafrost degradation due to climate warming, thermokarst lake was developing and undergoing substantial changes. Thermokarst an essential ecosystem component, which significantly impacted the global carbon cycle, hydrology process stability Qinghai–Tibet Engineering Corridor. In this paper, based on Sentinel-2 (2021) Landsat (1988–2020) images, lakes within a 5000 m range along both sides Highway were extracted analyse spatio-temporal...
Many ongoing tunnel projects provide a favorable opportunity for the investigation and application of lining ground heat exchangers (GHEs). Tunnel GHEs can be connected to pump extract geothermal energy heating cooling buildings. Numerous studies have focused on thermal performance GHEs; however, interaction between pumps are relatively rare. In this study, coupled transfer model was proposed then calibrated based in situ test results. The used evaluate efficiency with under different...
Previous studies have demonstrated the effectiveness of a novel three-layer landfill cover system constructed with recycled concrete aggregates (RCAs) without geomembrane in both laboratory and field. However, no systematic investigation has been carried out to optimize combination particle sizes for fine-grained RCAs (FRC) coarse-grained (CRC) that can be used system. The aim this paper is assist engineers designing under rainfall 100-year return period humid climate conditions using an...
