Special products for hydraulic concrete constructions . products for making structural joints between two concrete elements . test for determining the maximum assembly time 水硬性混凝土建筑用的特殊產(chǎn)品.粘結(jié)兩塊混凝土的產(chǎn)品.最大粘合時(shí)間測試
3d nonlinear finite element method is applied to analyze the stability of rock slope in the paper . when using this method , the thin layer element is used to simulate interlayer and structural joint for sliding surfaces 本文采用了合理模擬以夾層、結(jié)構(gòu)面等為滑動(dòng)面的薄層單元及相應(yīng)的非線性分析為基礎(chǔ)的三維非線性有限元解法來求解巖質(zhì)邊坡的穩(wěn)定性。
For better understanding the influence of tectonic structural features in soil mass to subgrade of infrastructure , the author defined the faults , structural joints and structural fissures as neogene tectonic structural planes , and studied the features of the planes with the methods of systematic analysis 摘要為闡明土體中存在的構(gòu)造形跡對(duì)工程建(構(gòu))筑物地基的影響,將土體中的斷層、構(gòu)造節(jié)理和構(gòu)造裂縫統(tǒng)稱為土體新近紀(jì)構(gòu)造結(jié)構(gòu)面,用系統(tǒng)分析方法對(duì)土體新近紀(jì)構(gòu)造結(jié)構(gòu)面特性進(jìn)行了分析。
Statistic analysis on fatigue load effect and equivalent stress range of steel crane structures in service is carried out . the stress range distribution in whole life is deduced by the spot measurement little sample stress - time process . meanwhile the statistic analysis on the fatigue resistance process is conducted , according to fatigue data of all kinds of structural joints in domestic and overseas , which is foundation with , establish the fatigue reliability model 2 、在大量調(diào)查的基礎(chǔ)上,對(duì)吊車梁所承受的疲勞荷載效應(yīng)與等效等幅應(yīng)力進(jìn)行了統(tǒng)計(jì)分析,同時(shí)根據(jù)國內(nèi)外有關(guān)各構(gòu)造細(xì)節(jié)的疲勞資料對(duì)疲勞抗力參數(shù)進(jìn)行了統(tǒng)計(jì)分析,為建立疲勞動(dòng)態(tài)可靠性分析模式奠定基礎(chǔ)。
