1) shallow large-section underground structure
浅埋大断面地下结构
1.
The urban shallow large-section underground structure has become important and difficult part of engineering because of the complexity of its structure and construction.
城市浅埋大断面地下结构因其结构和建设的复杂性往往成为工程建设的重点和难点。
2) embedded large-span corrugated steel culvert
地下大断面薄钢结构
1.
In order to clarify the dynamic and static stabilities of embedded large-span corrugated steel culverts,a series of scaled-model shaking table tests(two different types of 1/16-scaled models of the corrugated culvert),the field tests of the proto-type models and simulation analyses using finite element method were performed.
为明确地下大断面薄钢结构的安全实用性,进行1/16大断面薄钢结构的系列模型振动试验、实际规模结构的现场试验和有限元分析。
3) Shallow tunnel with big cross-section
大断面浅埋隧道
6) ultra-shallow-buried and ultra-high sectional tunnel
超浅埋超高断面
1.
The space-time sequence of tunnel excavation was optimized through the comparative analysis of simulation results with measured results and feedback design for construction of the ultra-shallow-buried and ultra-high sectional tunnel with underground excavation under the conditions of complex environment and weak-water rock.
研究目的:通过建立ANSYS仿真模型,研究隧道开挖引起的地层扰动对地表沉降和拱顶下沉2个重要安全控制指标的影响规律,从而控制地层应力重分布对施工安全和结构稳定带来的不利影响;实施地层变形仿真结果与实测结果的对比分析和反馈设计,优化隧道开挖步序,从而实现复杂环境、软弱富水围岩条件下超浅埋超高断面暗挖隧道的成功修建。
