【摘要】：隨著國(guó)際貿(mào)易往來(lái)越發(fā)頻繁,海洋經(jīng)濟(jì)得到迅速發(fā)展,港口已成為不可或缺的角色,碼頭更是其中重要的交通樞紐。當(dāng)碼頭被過(guò)度使用同時(shí)又無(wú)法及時(shí)維修時(shí),將導(dǎo)致碼頭出現(xiàn)不同程度的損傷,故分析碼頭結(jié)構(gòu)穩(wěn)定性對(duì)其正常運(yùn)營(yíng)具有重大意義。本文對(duì)高樁碼頭的破壞形式和損害原因進(jìn)行詳細(xì)闡述,根據(jù)碼頭為鋼筋混凝土結(jié)構(gòu),故通過(guò)對(duì)鋼筋混凝土結(jié)構(gòu)的檢測(cè),研究碼頭變形及失穩(wěn),分析鋼筋混凝土破壞的主要因素,研究其破壞機(jī)理,并從混凝土碳化、鋼筋銹蝕等分析碼頭結(jié)構(gòu)的耐久性和穩(wěn)定性。通過(guò)有限元軟件ABAQUS分別模擬船舶撞擊力、門(mén)機(jī)荷載、自重荷載和門(mén)機(jī)荷載、自重荷載兩種方式對(duì)碼頭結(jié)構(gòu)的穩(wěn)定性,根據(jù)模擬結(jié)果對(duì)比分析兩者間的差異。同時(shí),分析碼頭可靠度,對(duì)有限元軟件模擬的碼頭穩(wěn)定性與經(jīng)驗(yàn)公式計(jì)算可靠度結(jié)果進(jìn)行比較,得出如下結(jié)論:(1)從第四章可知,碼頭結(jié)構(gòu)在船舶撞擊力作用下,結(jié)構(gòu)應(yīng)力與位移會(huì)明顯增大,碼頭結(jié)構(gòu)更容易失穩(wěn),使碼頭處于危險(xiǎn)狀態(tài)。(2)通過(guò)經(jīng)驗(yàn)公式計(jì)算外力作用下碼頭結(jié)構(gòu)可靠度,得出可靠度與船舶撞擊力成反比,船舶撞擊力越大可靠度越小,而可靠度與碼頭穩(wěn)定性呈正向變化,可靠度越大碼頭越穩(wěn)定。(3)采用有限元模型模擬碼頭結(jié)構(gòu)受力,其穩(wěn)定性與計(jì)算得到的結(jié)果一致,說(shuō)明利用有限元方法預(yù)測(cè)碼頭結(jié)構(gòu)穩(wěn)定性可取�？傊�,本文通過(guò)分析高樁碼頭結(jié)構(gòu)的損害原因,采用有限元和經(jīng)驗(yàn)公式計(jì)算兩種方法預(yù)測(cè)碼頭結(jié)構(gòu)穩(wěn)定性和結(jié)構(gòu)耐久性,為碼頭正常運(yùn)營(yíng)奠定了基礎(chǔ)。
[Abstract]:With the more frequent international trade and the rapid development of marine economy, port has become an indispensable role, wharf is an important transportation hub. When the wharf is overused and can not be repaired in time, it will lead to different degrees of damage to the wharf, so it is of great significance to analyze the stability of the wharf structure for its normal operation. In this paper, the failure form and damage reason of high pile wharf are expounded in detail. According to the reinforced concrete structure of wharf, the deformation and instability of wharf are studied through the detection of reinforced concrete structure, and the main factors of failure of reinforced concrete are analyzed. The failure mechanism is studied, and the durability and stability of wharf structure are analyzed from carbonization of concrete and corrosion of steel bar. The stability of wharf structure is simulated by finite element software ABAQUS, which includes ship impact force, portal crane load, deadweight load and gantry load. The difference between them is analyzed according to the simulation results. At the same time, the reliability of wharf is analyzed, and the stability of wharf simulated by finite element software is compared with the result of calculating reliability by empirical formula. The conclusion is as follows: 1) from Chapter 4, we can know that the structure of wharf is under the action of ship impact force. The stress and displacement of the structure will obviously increase, and the structure of the wharf will be more vulnerable to instability, which makes the wharf in a dangerous state. (2) the reliability of the wharf structure under the action of external force is calculated by empirical formula, and the reliability is found to be inversely proportional to the impact force of the ship. The greater the impact force, the smaller the reliability, and the positive change between the reliability and the wharf stability, and the greater the reliability, the more stable the wharf is.) the finite element model is used to simulate the stress on the structure of the wharf. The stability is consistent with the calculated results. It is suggested that the finite element method can be used to predict the stability of wharf structure. In a word, by analyzing the damage reasons of the high pile wharf structure, the finite element method and the empirical formula are used to predict the stability and durability of the wharf structure, which lays a foundation for the normal operation of the wharf.
