A bearing surface transmits the interaction between an arch dam and its foundation , the strength of which directly affects the constraint of the bedrock to the dam , and thus affects the stress and deformation of the dam . the influence is studied in this paper with nonlinear finite element method , as an example , for a high arch dam in design . the results show that the influence on stress is only limited within the local area near the bearing surface , larger on the maximum principal tensile stress than on the principal compression stress , and the decrease of the strength does not cause unlimited increase of the maximum stress . the influence on the displacement of the top of the dam is smaller than that of the bottom of the dam , especially the relative downstream displacement . at the lower strength of the bearing surface , the relative downstream displacement at the bottom of the dam increases with the decrease of the strength 建基面是傳遞拱壩和基巖相互作用的紐帶,它的強(qiáng)度直接影響基巖對(duì)壩體的約束,從而影響壩體的應(yīng)力和變形.采用非線(xiàn)性有限單元法,以設(shè)計(jì)中的某高拱壩為例,分析建基面強(qiáng)度對(duì)壩體應(yīng)力和變形的影響.結(jié)果表明建基面強(qiáng)度對(duì)壩體應(yīng)力的影響僅限于建基面附近的局部范圍,對(duì)最大主拉應(yīng)力的影響要大于對(duì)最大主壓應(yīng)力的影響,建基面強(qiáng)度的降低不會(huì)無(wú)限地增大壩體的應(yīng)力數(shù)值;建基面強(qiáng)度對(duì)壩頂位移的影響較小,但對(duì)壩底位移(尤其是順河向相對(duì)位移)的影響較大,當(dāng)建基面強(qiáng)度較低時(shí),壩底順河向相對(duì)位移隨建基面強(qiáng)度的降低而增大
( 5 ) rock mass stability analysis on dam abutment of xia luo - yu damsite as follows : in left dam abutment , sideslip control structure has been relatively integrate , and low dip angle jointing did n ' t develop , so integrate sliding deformation control structure could n ' t been formed in three - dimensional space and rock mass stability could n ' t been influenced badly ; in right dam abutment , indicate rock mass distortion was caused by the rock mass mechanics condition , such as specific rock mass structure , compression stress concentrate with high strength and especial landform and so on ( 5 )對(duì)下落魚(yú)壩址壩肩巖體穩(wěn)定問(wèn)題的分析得出:左壩肩巖體雖然具有相對(duì)較完整的側(cè)滑控制結(jié)構(gòu),但由于緩傾角節(jié)理不發(fā)育,故在三維空間上不能形成完整的滑移變形控制結(jié)構(gòu),亦不會(huì)對(duì)壩肩巖體穩(wěn)定性產(chǎn)生嚴(yán)重影響:右壩肩巖體復(fù)雜變形,是在特定的巖體結(jié)構(gòu)、高強(qiáng)度的壓應(yīng)力集中及特殊的地形等不可或缺的巖體力學(xué)條件下產(chǎn)生的。
First of all , the structural characteristic and essential of damages were introduced . secondly the efficiency factor of how much the compression stress perpendicular to grain is more than the design value was calculated . thirdly , the main reason that members were made too large deformation and serious damage was pointed out 但是,目前木塔殘留的整體傾斜、層間側(cè)移以及由木材橫紋壓縮引起的豎向壓縮變形等都已達(dá)到嚴(yán)重影響其安全可靠的程度,所以,木材橫紋局壓增強(qiáng)加固問(wèn)題亟待解決,以防突變。
