The purpose of this paper is to solve the engineering problem that a large amount of soil and rock will be landfilled nearby along the canal for disposal and reuse.This study utilizes the ongoing Pinglu Canal project as a case study to propose several essential technologies applicable to different phases of soil and rock landfilling.These phases encompass site selection,design,construction,acceptance,and subsequent reuse.The proposed methods include establishing a suitability evaluation method for site selection based on remote sensing interpretation and UAV aerial photography.In the design stage,the focus is on making full use of the excavated soil and rock to construct retaining structures and ecological soil covers,ensuring both landfilling safety and environmentally friendly utilization.During the filling process,aerial surveys and in-situ testing techniques are employed to capture the temporal and spatial variation of the fill materials and obtain detailed physical and mechanical parameters for safety assessment of the containment project.For the high landfills exceeding 20 meters,a multifunctional land reclamation structure with anti-seepage,water retention,and fertility retaining functions is proposed,enabling safe and sustainable reuse of the land.The paper also recommends two kinds of suitability engineering technology,including rapid detection and classification of earth and rock by using image-based deep learning and modern sensing technologies,and ecological slope protection technology using flexible geosynthetic materials.
