本文介紹了基坑支護(hù)結(jié)構(gòu)的形式、特點(diǎn),以及目前工程中基坑的設(shè)計(jì)計(jì)算方法,分析了土壓力的計(jì)算在基坑工程設(shè)計(jì)計(jì)算中的重要性;通過(guò)實(shí)測(cè)的基坑主動(dòng)土壓力與支護(hù)結(jié)構(gòu)位移的分析得出基坑主動(dòng)土壓力與位移之間存在密切關(guān)系,在此基礎(chǔ)上以朗肯土壓力理論為前提建立了考慮基坑支護(hù)結(jié)構(gòu)位移的主動(dòng)區(qū)土壓力公式;并對(duì)公式中的主動(dòng)極限位移的計(jì)算做了研究,提出了主動(dòng)極限位移的兩種計(jì)算方法;把這兩種方法都運(yùn)用于考慮支護(hù)結(jié)構(gòu)位移的主動(dòng)土壓力計(jì)算公式,進(jìn)而結(jié)合工程實(shí)例,對(duì)考慮支護(hù)結(jié)構(gòu)位移的主動(dòng)土壓力公式進(jìn)行了驗(yàn)證,驗(yàn)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 combinative 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(shí)行信息化施工并獲得了豐富的監(jiān)測(cè)數(shù)據(jù)，通過(guò)對(duì)數(shù)據(jù)分析結(jié)果表明：實(shí)測(cè)主動(dòng)土壓力小于計(jì)算主動(dòng)土壓力，實(shí)測(cè)主動(dòng)土壓力隨時(shí)間延長(zhǎng)變?。和馏w中孔隙水壓力隨時(shí)間增長(zhǎng)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(xié)同作用明顯，冠梁減小了基坑變形；錨索軸力比較穩(wěn)定，鋼撐軸力變化相對(duì)較大，且二者軸力仍富余較大，該設(shè)計(jì)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 utility of mohr - coulomb strength criterion in the two - dimensional stress state make a blemish that the active soil pressure is bigger and the passive soil pressure is litter than the real
朗肯土壓力計(jì)算公式一直是工程實(shí)際土壓力計(jì)算的理論基礎(chǔ)，但是朗肯土壓力計(jì)算公式在推導(dǎo)過(guò)程中忽略了中主應(yīng)力的影響，仍然應(yīng)用二維應(yīng)力狀態(tài)下的莫爾?庫(kù)侖強(qiáng)度準(zhǔn)則，致使計(jì)算出的主動(dòng)土壓力偏大而被動(dòng)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 establishes model of general structure finite element of this bridge , and in details analyses its qualities 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 qualities 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 establishes the model of plane frame by applying large common software - 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 established , and unique stress and performance of structure of semi - integral abutment jointless bridge are researched by comparing and analysing character of three different models under same loading , and controlling factor of design and constitution are generalized . 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 eliminated , 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 application and popularization
半整體式橋臺(tái)無(wú)縫橋梁計(jì)算模型考慮了上部結(jié)構(gòu)-下部結(jié)構(gòu)-土的共同作用；臺(tái)后土抗力升溫時(shí)采用靜止土壓力加彈性土抗力，降溫時(shí)采用主動(dòng)土壓力；分析橋梁受力性能時(shí)考慮了結(jié)構(gòu)自重、車輛荷載和季節(jié)性溫變荷載的作用。以一座橋長(zhǎng)100mpc半整體式橋臺(tái)無(wú)縫橋梁為實(shí)例，采用大型通用軟件ansys建立平面框架模型，進(jìn)行彈性、大變形分析，模擬全橋受力和變形特點(diǎn)；同時(shí)建立與此對(duì)應(yīng)的有伸縮縫橋梁和整體式橋臺(tái)無(wú)縫橋梁有限元模型，通過(guò)三種橋型同步加載對(duì)比分析，研究半整體式橋臺(tái)無(wú)縫橋梁獨(dú)特的受力特點(diǎn)和結(jié)構(gòu)性能，總結(jié)其設(shè)計(jì)控制因素和構(gòu)造要求。通過(guò)本文研究知：半整體式橋臺(tái)無(wú)縫橋梁主梁的剪力、彎矩、撓度和下部結(jié)構(gòu)的軸力與梁式橋相近，結(jié)構(gòu)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(jié)構(gòu)剪力、彎矩較梁式橋大；綜合分析是一種受力合理有實(shí)踐和推廣價(jià)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
