【摘要】：提出了模型試驗(yàn)的分離相似設(shè)計(jì)方法,以錨索、格構(gòu)梁加固邊坡振動(dòng)臺(tái)試驗(yàn)為例進(jìn)行介紹。將傳統(tǒng)量綱分析法中描述振動(dòng)臺(tái)試驗(yàn)各個(gè)相關(guān)參數(shù)之間關(guān)系的函數(shù)關(guān)系式定義為1級(jí)特征方程。根據(jù)邊坡、錨索、格構(gòu)和地震波特性的不同,將1級(jí)特征方程進(jìn)行分離處理,得到分別用于邊坡、錨索、格構(gòu)和地震波相似設(shè)計(jì)的2級(jí)特征方程。根據(jù)每個(gè)2級(jí)特征方程中參數(shù)的重要程度不同,將關(guān)鍵設(shè)計(jì)參數(shù)從2級(jí)特征方程中分離出來,組成3級(jí)特征方程。根據(jù)3級(jí)、2級(jí)和1級(jí)特征方程可以分別推導(dǎo)得到針對(duì)邊坡、錨索、格構(gòu)梁和地震波各自的關(guān)鍵參數(shù)、相關(guān)參數(shù)和無關(guān)參數(shù)相似比,選擇關(guān)鍵參數(shù)相似比作為模型設(shè)計(jì)的主要依據(jù),并對(duì)試驗(yàn)?zāi)Ｐ瓦M(jìn)行了相似設(shè)計(jì)。解決了按照傳統(tǒng)量綱分析法要求,模型試驗(yàn)無法同時(shí)滿足所有參數(shù)相似比要求的問題。
[Abstract]:A separate similarity design method for model test is presented, and an example of shaking table test for reinforcement of slope with anchor cable and lattice beam is introduced. This paper defines the function relation of the traditional dimensionality analysis method which describes the relation between the parameters of the shaking table test as the first order characteristic equation. According to the different characteristics of slope, anchor cable, lattice and seismic wave, the one-order characteristic equation is separated and treated, and the two-order characteristic equation is obtained for the similar design of slope, anchor cable, lattice structure and seismic wave, respectively. According to the different importance of the parameters in each two-order characteristic equation, the key design parameters are separated from the two-order characteristic equation to form the third-order characteristic equation. According to the characteristic equations of stage 2 and order 1, the similarity ratios of key parameters, correlation parameters and independent parameters for slope, anchor cable, lattice beam and seismic wave can be derived, respectively. The similarity ratio of key parameters is chosen as the main basis of model design, and the similarity design of test model is carried out. According to the requirement of traditional dimensional analysis, the model test can not satisfy the requirement of similarity ratio of all parameters at the same time.
