【摘要】：對(duì)工程場(chǎng)地進(jìn)行地震安評(píng)工作時(shí),要用到場(chǎng)地地震動(dòng)參數(shù)。場(chǎng)地地震動(dòng)參數(shù)主要為場(chǎng)地地震動(dòng)峰值(峰值加速度、峰值速度、峰值位移)、反應(yīng)譜與時(shí)程強(qiáng)度包絡(luò)函數(shù)等。其中,最為常用的為地震動(dòng)峰值加速度與加速度反應(yīng)譜。一維分析模型進(jìn)行地震反應(yīng)分析主要應(yīng)用于地面、土層及基巖面較為平坦的場(chǎng)地,目前主流的程序有LSSRLI-1與SHAKE2000。二者的都是基于等效線性化方法來(lái)計(jì)算土層地震反應(yīng)的程序。其中,國(guó)內(nèi)目前廣泛應(yīng)用的LSSRLI-1等效線性化程序起始于上世紀(jì)80年代,與目前代表國(guó)際先進(jìn)水平的SHAKE2000存在一些計(jì)算結(jié)果上的差異。本文以SHAKE2000為參照,對(duì)比二者的計(jì)算結(jié)果,了解其差異所在,為下一步的程序改進(jìn)工作提供基礎(chǔ)。本文主要內(nèi)容為:1、介紹國(guó)內(nèi)土層反應(yīng)分析方法的研究現(xiàn)狀,介紹等效線性化方法,介紹LSSRLI-1與SHAKE2000兩個(gè)程序。2、構(gòu)造理想計(jì)算剖面,選取輸入地震波與土的非線性曲線。3、利用LSSRLI-1與SHAKE2000兩個(gè)程序,對(duì)四種類型的場(chǎng)地進(jìn)行計(jì)算,對(duì)比地表峰值加速度、地表加速度反應(yīng)譜與土層剪應(yīng)變之間的差異,總結(jié)其規(guī)律。4、將四類場(chǎng)地在兩種非線性條件下的計(jì)算結(jié)果進(jìn)行整體分析,得到兩個(gè)程序間差異與場(chǎng)地分類、輸入地震波、土的非線性條件的關(guān)系,得到LSSRLI-1與SHAKE2000計(jì)算出的地表反應(yīng)差異的一般性規(guī)律。
[Abstract]:Ground motion parameters should be used in seismic safety assessment of engineering site. The parameters of ground motion are mainly the peak value of ground motion (peak acceleration, peak displacement), response spectrum and time-history intensity envelope function. Among them, the most commonly used is the peak acceleration and acceleration response spectrum of ground motion. The seismic response analysis based on one-dimensional analysis model is mainly used in the field where the surface, soil layer and bedrock surface are relatively flat. At present, the main programs are LSSRLI-1 and SHAKE2000. Both programs are based on the equivalent linearization method to calculate the seismic response of soil layer. The LSSRLI-1 equivalent linearization program, which is widely used in China at present, started in the 1980s, and there are some differences between the results of calculation and that of SHAKE2000, which represents the international advanced level. In this paper, SHAKE2000 is used as a reference to compare the results of their calculations, to understand the differences, and to provide a basis for the next work of program improvement. This paper introduces the research status of soil layer response analysis method in China, introduces the equivalent linearization method, and introduces two programs, LSSRLI-1 and SHAKE2000, to construct the ideal calculation profile. Selecting the nonlinear curve of input seismic wave and soil. 3, using LSSRLI-1 and SHAKE2000 program to calculate four kinds of sites, comparing the difference between the peak acceleration, the response spectrum of ground acceleration and the shear strain of soil layer. Summing up its rule. 4, the results of four kinds of sites under two nonlinear conditions are analyzed as a whole, and the relationship between the difference between the two programs and the site classification, the input of seismic wave and the nonlinear condition of soil is obtained. The general law of surface response difference calculated by LSSRLI-1 and SHAKE2000 is obtained.
