This paper deals with seismic response of a tunnel - soil system immersed tunnel ， as an underground structure ， must be compatible with the deformation of the surrounding soil thus the simplified model for a tunnel - soil system is established through two steps at the first step ， an mdof system is developed for modeling the foundation soil to this end ， dynamic behavior of the foundation soil is analyzed a typical section of the foundation soil simplified as a single mass - spring system on the basis of some equivalent criteria those mass are linked longitudinally by elastic springs to form an mdof system at the second step ， the tunnel is treated as a beam on elastic foundation ; that is ， the tunnel is connected with the soil massed to form a tunnel - soil system this model has been applied to the seismic analysis of huangsha fangcun immersed tunnel across the pearl river in guangzhou design recommendation is proposed on the basis of this analysis
研究沉管隧道在地震條件下整體受力的分析方法分兩步建立計算模型第一步通過分析場地地基土切片的動力特性，根據等效原則將其化為等效單質點體系，然後在縱向用等效彈簧連接而成為多質點體系的地基土計算模型；第二步將隧道看作彈性地基梁與上述多質點體系通過等效彈簧連結而得到土隧道體系的計算模型本文結合廣州黃沙芳村珠江水下隧道工程實例建立了具體的計算模型並對多種不同的約束條件，進行了縱向與橫向地震響應時程分析，為該隧道的抗震設計提供依據On the basis of general introduction of the all - american canal system and the all - american canal irrigation district, the facilities ( dams, desilting works, irrigation canal system ), project management and maintenance, and benefits of all - american canal system were de scribed and analyzed in detail
