【摘要】：隨著經(jīng)濟(jì)發(fā)展以及工業(yè)、農(nóng)業(yè)用電的持續(xù)增長(zhǎng)，各地電力建設(shè)項(xiàng)目不斷增長(zhǎng)。其中，核能發(fā)電在整個(gè)能源發(fā)電領(lǐng)域中占據(jù)著重要的作用，它是國(guó)家鼓勵(lì)發(fā)展的清潔能源，在當(dāng)前宏觀擴(kuò)大內(nèi)需的形勢(shì)下，，核能發(fā)電的建設(shè)步伐正在加快。但核工程的安全性一直是全世界人們普遍關(guān)注的問題，尤其是自日本東北海域發(fā)生的地震造成了七級(jí)核泄漏以來，全世界對(duì)核工程抗震安全性的要求已變得刻不容緩，因此研究核工程其中的一個(gè)薄弱環(huán)節(jié)，管道系統(tǒng)，有很重要的現(xiàn)實(shí)意義。 為此，本文依托某項(xiàng)目，通過理論研究、數(shù)值模擬以及實(shí)例分析等手段對(duì)核工程管道系統(tǒng)及所用支架進(jìn)行了抗震分析研究。主要研究?jī)?nèi)容如下： （1）對(duì)比國(guó)內(nèi)外強(qiáng)震記錄，根據(jù)各強(qiáng)震記錄的包絡(luò)情況，提出適用于核工程管道系統(tǒng)抗震校核的地震反應(yīng)譜； （2）運(yùn)用有限元理論及不同的地震響應(yīng)分析方法，對(duì)比現(xiàn)階段三種不同的管道應(yīng)力計(jì)算軟件，分析確定適用性； （3）利用振型分解反應(yīng)譜法，結(jié)合工程實(shí)例，對(duì)比分析了不同剛度約束條件下的管道系統(tǒng)的抗震性能，同時(shí)指出在通常情況下，管道系統(tǒng)的危險(xiǎn)截面位于三通及彎頭截面處； （4）運(yùn)用現(xiàn)階段抗震計(jì)算通常采用的底部剪力法與時(shí)程分析法，著重研究對(duì)比了兩種方法下，管系所用支架的地震響應(yīng)情況，指出支架所處的危險(xiǎn)截面，對(duì)比了不同地震波作用下的管道抗震性能及對(duì)應(yīng)的地震響應(yīng)特性； （5）結(jié)合支架的時(shí)程響應(yīng)，對(duì)管系支架進(jìn)行抗震可靠性分析，確定影響支架可靠性的主次因素及相關(guān)性，并研究了地面峰值加速度與結(jié)構(gòu)可靠度的關(guān)系。
[Abstract]:With the development of economy and the continuous growth of electricity consumption in industry and agriculture, the electric power construction projects in various places are increasing. Among them, nuclear power generation plays an important role in the field of energy generation. It is a clean energy encouraged by the state, in the current situation of expanding domestic demand macro, the pace of nuclear power generation is accelerating, but the safety of nuclear engineering has been a universal concern all over the world. Especially since the earthquake in northeast Japan caused a magnitude 7 nuclear leakage, the requirement of seismic safety of nuclear engineering has become urgent all over the world, so the study of nuclear engineering is a weak link. Pipeline system, has very important practical significance. Therefore, based on a project, through theoretical research, numerical simulation and case analysis, this paper studies the seismic analysis of nuclear engineering pipeline system and its support. The main research contents are as follows: 1) comparing the strong earthquake records at home and abroad, according to the envelope of each strong earthquake record, the seismic response spectrum suitable for seismic verification of nuclear engineering pipeline system is put forward. 2) using the finite element theory and different seismic response analysis methods, comparing three different kinds of pipeline stress calculation software at the present stage, analyzing and determining the applicability; 3) the seismic performance of pipeline system under different stiffness constraints is compared and analyzed by using the mode decomposition response spectrum method and engineering examples, and it is pointed out that the seismic behavior of pipeline system under normal conditions is also pointed out. The dangerous section of pipeline system is located at the section of three-way and elbow; 4) by using the method of bottom shear force and time-history analysis, the seismic response of the support used in the pipe system is studied and compared, and the dangerous section of the support is pointed out. The seismic behavior and the corresponding seismic response of pipeline under different seismic waves are compared. Combined with the time history response of the support, the aseismic reliability of the pipe support is analyzed, and the primary and secondary factors affecting the reliability of the support are determined, and the relationship between the peak acceleration of the ground and the reliability of the structure is studied.
