Abstract

A novel composite lining has been proposed by setting steel tube, self-compacted concrete (SCC) and composite plastic drainage board (CPDB) inside the segmental lining in a water conveyance tunnel through urban areas. The CPDB between the SCC and the segmental lining affects the performance of the lining. The potential sliding between the steel tube and SCC, as well as between the SCC and segmental lining, has a substantial impact on the structural bearing capacity. Therefore, the finite element model of the composite lining was built based on the concrete damage plasticity model and the Coulomb friction model. The bearing ratio of each layer before and after fracture failure of the SCC were analyzed. It was found that the internal water pressure is mainly shared by surrounding rock. The bearing ratio of the steel tube is significantly lower than expected. Consequently, the design method of the composite lining was proposed based on the d/E of the CPDB (the ratio of the thickness d to its comprehensive elastic modulus E). The design philosophy of the novel composite lining is that the steel tube shares most of the internal water pressure. It can be achieved by controlling the d/E within the range of 12.4–45.1 mm³/N. Also, the crack resistance of the segmental lining and the allowable steel tube stress are satisfied.

期刊介绍： Pressure vessel engineering technology is of importance in many branches of industry. This journal publishes the latest research results and related information on all its associated aspects, with particular emphasis on the structural integrity assessment, maintenance and life extension of pressurised process engineering plants. The anticipated coverage of the International Journal of Pressure Vessels and Piping ranges from simple mass-produced pressure vessels to large custom-built vessels and tanks. Pressure vessels technology is a developing field, and contributions on the following topics will therefore be welcome: • Pressure vessel engineering • Structural integrity assessment • Design methods • Codes and standards • Fabrication and welding • Materials properties requirements • Inspection and quality management • Maintenance and life extension • Ageing and environmental effects • Life management Of particular importance are papers covering aspects of significant practical application which could lead to major improvements in economy, reliability and useful life. While most accepted papers represent the results of original applied research, critical reviews of topical interest by world-leading experts will also appear from time to time. International Journal of Pressure Vessels and Piping is indispensable reading for engineering professionals involved in the energy, petrochemicals, process plant, transport, aerospace and related industries; for manufacturers of pressure vessels and ancillary equipment; and for academics pursuing research in these areas.
