Abstract:
Along with the rapid development of international metropolis, China's urbanization is developing faster and faster. In the process of China's urbanization development, mountain mounding with construction waste is one of the most direct, effective and economical means to deal with construction waste, not only that, but also, one of the important methods for ecological restoration project of landscape gardening, this method has several advantages such as green construction, green low carbon, energy saving and carbon reduction, etc. It also improves the utilization rate of resources, has high economic and environmental benefits, and also has high High research value and social significance.Since there are differences in the mechanical properties of the original soil and the mounded hill materials in the process of construction waste mounding, as well as, differences in the soil quality in different regions, it is necessary to study the stability of the hill. In this paper, the following research results are obtained through actual case studies of typical landscape projects: first, geomechanical tests are conducted on the raw soil and construction waste mound hill materials to obtain the particle size ratios, maximum dry density and optimum moisture content, and compression modulus of specific mixes, and the triaxial shear test proves that each stress-strain curve basically conforms to the Duncan-Zhang hyperbolic relationship assumption before the peak occurs.Finally, numerical simulations were carried out for different working conditions in combination with the three-dimensional calculation model, and the calculation and analysis of the Bishop consolidation theory were used to obtain the settlement displacement, horizontal displacement development and pore pressure dissipation process of the calculation model. The landslide stability of the slope is calculated and the minimum safety coefficient under normal conditions and the minimum safety coefficient under seismic conditions are both calculated by Swedish method and Bishop method respectively, both of which meet the requirements and determine the technical feasibility and reasonableness of the scheme. In the conclusion part of this paper, the problems and handling measures in the construction process are summarized to provide valuable experience for similar projects.Keywords:

This article is concerned with the design and construction of the Renfrew motorway sewer, which was built to avoid overloading Glasgow's existing sewerage system. Particular reference is made to the problems created by the presence of underground railway tunnels, poor ground, the depressed motorway profile and the need to minimize tidal effect. After a general introduction the author discusses design criteria and the choice of a suitable route which passed under the underground railway. This includes a discussion of the factors which led to the type and method of construction used. The next part of the article is concerned with the actual construction work, and includes details of the equipment used which included a stelmo shield in the soft ground tunnel and of the tunnel lining. It also includes information relating the blasting methods that were used and the laying and backfilling of the pipes which involved the use of an aliva 300 concrete placing machine. Reference is made to the caulking of joints which was carried out to overcome the problem of containing the compressed air used in the construction in the sheet pile shafts and at the junction with the air deck. /TRRL/
