【摘要】：每年世界各地的地震災(zāi)害都會(huì)造成大量人員傷亡及巨大的經(jīng)濟(jì)損失,因此對地震的研究很早就開始了,在對歷史震害進(jìn)行大量分析后發(fā)現(xiàn)場地條件對震害有很大的影響。為了在抗震計(jì)算時(shí)定量地體現(xiàn)這種影響,我國早就《建筑抗震設(shè)計(jì)規(guī)范》內(nèi)引入了場地類別、抗震設(shè)防等級(jí)、地震影響系數(shù)α曲線等。但當(dāng)進(jìn)行抗震計(jì)算的建筑的場地條件需要細(xì)分或者建筑很重要的情況下就需要利用時(shí)程法進(jìn)行反應(yīng)分析。以往人們都是先現(xiàn)場鉆孔獲得土層數(shù)據(jù)再實(shí)驗(yàn)獲得土動(dòng)力參數(shù),最后手工輸入鉆孔資料計(jì)算,這樣不僅費(fèi)時(shí)費(fèi)力且容易造成人為失誤。當(dāng)前巖土工程的數(shù)據(jù)量越來越大工程結(jié)構(gòu)越來越復(fù)雜,這使得原先那種簡單數(shù)據(jù)形式已經(jīng)很難滿足要求了。近些年來興起的大數(shù)據(jù)技術(shù)就能很好地解決這個(gè)問題,本文就是利用該技術(shù)編寫了 Matlab下的反應(yīng)計(jì)算,并嵌入了大數(shù)據(jù)平臺(tái)。本文首先簡述了地震加速度反應(yīng)譜的研究現(xiàn)狀,介紹了計(jì)算模型及計(jì)算理論,在此基礎(chǔ)上介紹了該程序Matlab計(jì)算流程。然后利用該模塊杭州地區(qū)幾個(gè)Ⅱ,Ⅲ,Ⅳ類場地條件下輸入兩組人造地震動(dòng)求得反應(yīng)譜及動(dòng)力系數(shù)α、動(dòng)力放大系數(shù)最大值βmax等參數(shù)以此來分析計(jì)算模塊的合理性及精度。對于大數(shù)據(jù)處理本程序連接的杭州市巖土工程數(shù)據(jù)庫。之后用該程序計(jì)算了杭州市的一個(gè)工程實(shí)例以此來認(rèn)識(shí)該程序的操作流程。最后筆者總結(jié)分析該程序的特點(diǎn),并提出不足之處及相應(yīng)解決方案,希望能為大數(shù)據(jù)反應(yīng)譜計(jì)算領(lǐng)域提供一點(diǎn)參考作用。
[Abstract]:Every year, earthquake disasters around the world will cause a large number of casualties and huge economic losses, so the study of earthquakes began very early. It is found that the site condition has a great influence on the earthquake damage after analyzing the historical earthquake damage. In order to reflect this effect quantitatively in the seismic calculation, the site category has been introduced into the Code for Seismic Design of buildings in our country for a long time. Grade of seismic fortification. The seismic influence coefficient 偽 curve, etc. But when the site condition of the seismic calculation needs to be subdivided or the building is very important, it is necessary to use the time-process method to carry out the response analysis. In the past, people used to drill holes in the field first to obtain the response. Soil dynamic parameters were obtained by experiments. Finally, manual input of borehole data calculation is not only time-consuming and laborious, but also easy to cause human error. At present, the amount of data of geotechnical engineering is more and more large and the engineering structure is becoming more and more complex. This makes it difficult to meet the requirements in the form of simple data. Big data technology, which has emerged in recent years, is a good solution to this problem. In this paper, the response calculation under Matlab is compiled and embedded in the big data platform. Firstly, the research status of seismic acceleration response spectrum is briefly described, and the calculation model and calculation theory are introduced. On this basis, the program Matlab calculation flow is introduced, and then two sets of artificial ground motions are inputted to obtain the response spectrum and the dynamic coefficient 偽 under the condition of several sites of class 鈪，
