【摘要】：我國(guó)南方大部分地區(qū)常年遭受洪澇自然災(zāi)害的主要原因是因?yàn)榈貐^(qū)地勢(shì)低洼，汛期江水位升高，江水上灘造成大量的淹沒(méi)，形成洪泛區(qū)，且區(qū)域內(nèi)產(chǎn)生的澇水不能及時(shí)排放，因此需要沿江修建防洪堤才可以抵御洪水的侵入，與此同時(shí)配套修建排澇泵站及其它排澇設(shè)施及時(shí)排放澇水，才能徹底解決區(qū)域水患。 南面溝泵站位于海南省�？谑行缕骆�(zhèn)南面溝出口處，承擔(dān)區(qū)域澇水集中抽排的任務(wù)，南面溝泵站位于新坡鎮(zhèn)南部，處于地震不利的地段，根據(jù)2001年《中國(guó)地震動(dòng)參數(shù)區(qū)劃圖》的劃分，工程場(chǎng)地地震動(dòng)峰值加速度為0.30g，相當(dāng)于地震基本烈度為8度，鑒于泵站的重要性，要確保泵站的安全運(yùn)行和泵站在地震作用下的穩(wěn)定性，由于地震作用而產(chǎn)生的動(dòng)水壓力成為重要因素之一，因此需要深入研究結(jié)構(gòu)和動(dòng)水壓力之間的相互反應(yīng)。本文的內(nèi)容有以下幾點(diǎn)： 1、本文講述了泵站的國(guó)內(nèi)外發(fā)展史、研究課題的意義和目的以及介紹了地震反應(yīng)分析的現(xiàn)狀。 2、講述了泵站抗震的有限元理論分析的兩種方法：一種是反應(yīng)譜法，另一種是時(shí)程分析法，并對(duì)兩種方法進(jìn)行了比較，另外還介紹了土與結(jié)構(gòu)之間相互作用的理論與研究方法。 3、提出了流固耦合的有限元理論分析與方法，對(duì)幾種方法的理論分別作了簡(jiǎn)單介紹。 4、結(jié)合南面溝泵站工程的實(shí)例，，對(duì)結(jié)構(gòu)的抗震安全度進(jìn)行綜合的分析評(píng)價(jià)，得出的結(jié)論為以后的工程設(shè)計(jì)提供了一些參考價(jià)值。
[Abstract]:The main reason why most areas in the south of China suffer from the perennial flood and waterlogging natural disasters is that the area is low lying, the water level of the river rises in the flood season, the river beach causes a large amount of inundation, which forms the floodplain area, and the flood water produced in the area cannot be discharged in time. Therefore, it is necessary to build flood control embankment along the river to resist the flood invasion, and at the same time to build the drainage pump station and other drainage facilities to discharge the flood water in time, so that the regional flood hazard can be solved thoroughly. The south side ditch pumping station is located at the south side ditch exit of Xinpo Town, Haikou City, Hainan Province. It undertakes the task of centralized drainage of waterlogged water in the region. The south side ditch pump station is located in the south of Xinpo Town, where the earthquake is unfavorable. According to the division of the "China ground motion parameter zoning map" in 2001, the peak acceleration of the ground motion of the engineering site is 0.30g, which is equivalent to the basic earthquake intensity of 8 degrees. In view of the importance of the pumping station, In order to ensure the safe operation of pumping station and the stability of pumping station under earthquake, the dynamic water pressure caused by earthquake is one of the important factors, so it is necessary to deeply study the interaction between structure and dynamic water pressure. The contents of this article are as follows: 1. This paper describes the history of development of pumping stations at home and abroad, the significance and purpose of the research and the present situation of seismic response analysis. 2. Two methods of finite element theory analysis of earthquake resistance of pumping stations are described: one is the response spectrum method, the other is the time-history analysis method, and the two methods are compared. In addition, the theory and research methods of the interaction between soil and structure are introduced. 3. The finite element analysis and method of fluid-solid coupling are presented, and the theories of several methods are briefly introduced. 4. Combined with the example of Nanmianggou pumping station project, the seismic safety degree of the structure is analyzed and evaluated synthetically, and the conclusion provides some reference value for the future engineering design.
