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 -
During 11 years, the corporateion grew strong step by step ? form single products to various products, form innervarious waterproof to outerconstruct waterproof ; from material sale to project service ; from products sale to waterproof plan designing. and the saite personnel tried their all efforts to make the corporation strong, undertook the great responsibility of developing waterproof career in china, and persisted the conception of not selling materials but system, and provided complete waterproof system plan to every client
11年來，公司從單一品種到多樣品種；從結構內防水到結構外防水；從材料銷售到工程服務；從產品銷售到防水方案設計，賽特人勵精圖治，執著追求，肩負"致力於發展中國的防水事業"宏偉責任，以「賣系統，不只賣材料」的防水理念，將全方位的防水系統解決方案帶給每一個顧客。 -
In order to construct the bridges successfully, an exact analysis must be carried out in every construction step. yongan bridge is a cable - stayed bridge of tri - tower with single cable plane. integral cast - in - place construction on form board method is used in construction
因此，有必要對該橋的整個施工過程進行詳細的研究，合理安排橫梁預應力筋和斜拉索的張拉步驟及張拉量，以指導該橋施工。 -
It was shown that when the soil pressure on the stepped rsrw was relatively small, its distribution form was zigzag, and would be affected evidently by unloading function of the step ; the potential fracture surface of the stepped rsrw was obviously different from the 0. 3h fracture surface proposed by the usual hypothesis, and would change with height - width ratio of the wall ; finally, its deformation characteristics were different from the vertical rsrw with single step
測試表明：臺階式加筋土擋墻的墻後土壓力較小，呈鋸齒形分佈，明顯受臺階卸載的影響；潛在破裂面與0 . 3h破裂面假定有較大差異，並隨擋墻的高寬比變化而變化；變形特徵不同於單級直立式擋墻。
