文摘:基于土的塑性極限分析理論，從擋土墻最小抗傾覆安全系數和擋土墻背上的最大主動土壓力兩個角度，分別研究了坦墻后土體中第二破裂面的位置，認為在復雜的擋土結構墻背條件下，用最小抗傾覆安全系數來研究擋土墻后土體的破壞機制較為合理。

本文介紹了基坑支護結構的形式、特點,以及目前工程中基坑的設計計算方法,分析了土壓力的計算在基坑工程設計計算中的重要性;通過實測的基坑主動土壓力與支護結構位移的分析得出基坑主動土壓力與位移之間存在密切關系,在此基礎上以朗肯土壓力理論為前提建立了考慮基坑支護結構位移的主動區土壓力公式;并對公式中的主動極限位移的計算做了研究,提出了主動極限位移的兩種計算方法;把這兩種方法都運用于考慮支護結構位移的主動土壓力計算公式,進而結合工程實例,對考慮支護結構位移的主動土壓力公式進行了驗證,驗證了公式的合理性。

It was shown that the measured active soil pressures were smaller than the theoretical values and diminished with time , the measured pore water pressure decreased with the time and increased with the depth of soil , the binative effects of cap girder and supporting structure were obvious which diminished the displacement of foundation pits , and the measured axial force of the anchor and interior steel beam were far less than the design force , indicating that the design safety factor of the foundation pit was too large to be economical
基坑工程實行信息化施工并獲得了豐富的監測數據，通過對數據分析結果表明：實測主動土壓力小于計算主動土壓力，實測主動土壓力隨時間延長變小：土體中孔隙水壓力隨時間增長而減小，孔隙水壓力隨深度增加而呈非線性增加；基坑冠梁協同作用明顯，冠梁減小了基坑變形；錨索軸力比較穩定，鋼撐軸力變化相對較大，且二者軸力仍富余較大，該設計比較安全。

The rankine soil pressure theory is always accepted as the foundation of calculations of the soil pressure in practice . but as we know , the ignorance of the middle principal stress and the utipty of mohr - coulomb strength criterion in the o - dimensional stress state make a blemish that the active soil pressure is bigger and the passive soil pressure is ptter than the real
朗肯土壓力計算公式一直是工程實際土壓力計算的理論基礎，但是朗肯土壓力計算公式在推導過程中忽略了中主應力的影響，仍然應用二維應力狀態下的莫爾?庫侖強度準則，致使計算出的主動土壓力偏大而被動土壓力偏小。

This paper , in allusion to damage of expansion joint of bridge , introduces a sort of new structure of jointless device - semi - integral abutment jointless bridge , and estabpshes model of general structure finite element of this bridge , and in details analyses its quapties of stress . the model considers the interaction of superstructure - substructure - soil . resistance of the soil behind abutment adopts still soil pressure and elastic resistance when the temperature rising , but active soil pressure when dropping . analysis of quapties stress of bridge includes of action of dead load , car load , temperature load of season character . taking an 100m length pc semi - integral abutment jointless bridge as instance , the paper estabpshes the model of plane frame by applying large mon sofare - anasys , and analyses it by elastane and large deformation to imitate character of stress and deformation of general bridge . at the same time corresponding models of finite element of joint bridge and integral abutment bridge are estabpshed , and unique stress and performance of structure of semi - integral abutment jointless bridge are researched by paring and analysing character of three different models under same loading , and controlpng factor of design and constitution are generapzed . in conclusion , for semi - integral abutment jointless bridge , on one hand shear , moment and deflection of the main beam and axis force of substructure are approximate with that of joint bridge , and integral stifmess of structure is increased and damage of expansion joint is epminated , on the other hand there is axis force in main beam , shear and moment of substructure are bigger than that of joint bridge . in all this type of jointless bridge has rational stress and is worth of apppcation and popularization
半整體式橋臺無縫橋梁計算模型考慮了上部結構-下部結構-土的共同作用；臺后土抗力升溫時采用靜止土壓力加彈性土抗力，降溫時采用主動土壓力；分析橋梁受力性能時考慮了結構自重、車輛荷載和季節性溫變荷載的作用。以一座橋長100mpc半整體式橋臺無縫橋梁為實例，采用大型通用軟件ansys建立平面框架模型，進行彈性、大變形分析，模擬全橋受力和變形特點；同時建立與此對應的有伸縮縫橋梁和整體式橋臺無縫橋梁有限元模型，通過三種橋型同步加載對比分析，研究半整體式橋臺無縫橋梁獨特的受力特點和結構性能，總結其設計控制因素和構造要求。通過本文研究知：半整體式橋臺無縫橋梁主梁的剪力、彎矩、撓度和下部結構的軸力與梁式橋相近，結構整體剛度增大，并除去了伸縮縫病害；但主梁增加了軸力，下部結構剪力、彎矩較梁式橋大；綜合分析是一種受力合理有實踐和推廣價值的橋型。

The conclusion is that it is more similar to practical soil pressure distribution if shear strength parameters are used which are obtained by the experiments that can simulate the actual process of active soil during excavation . so it is more reasonable to use shear strength parameters obtained by tri - axial experiments that can simulate the process of excavation in design of retaining structure
本論文得出的結論是：用模擬基坑開挖實際應力路徑的試驗方法得出的抗剪強度指標計算基坑側土壓力分布，與實際情況更為接近，在基坑支護設計中，應該盡量使用模擬基坑開挖實際應力路徑的三軸試驗方法確定土體抗剪強度指標。
