Triple tube rigid type rotary corer 三重管雙動(dòng)回轉(zhuǎn)取土器
He has never been a rigid type of executive , having managed to preserve an easygoing manner instead 他從來都不是強(qiáng)硬作風(fēng)的經(jīng)理人,而是一直保持著平易近人的風(fēng)格。
The method could accurately reflect the influence of the modulus and thickness of semi - rigid type base on the cement concrete pavement thermal stresses 為此,通過大量的計(jì)算分析,本文建立了以溫度應(yīng)力等效為原則的基頂當(dāng)量回彈模量換算方法。
To the northwest area climate , to use the glasgrid which has the next characters : the high tensile strength , the low elongation , the high modulus of elasticity and so on , to absorb the crack of asphalt pavement on a semi - rigid type 計(jì)算、實(shí)驗(yàn)室試驗(yàn)及最終的現(xiàn)場(chǎng)試驗(yàn)表明,對(duì)試驗(yàn)路? ?寧夏古王高速公路而言,采取加鋪玻璃纖維格柵來降低溫縮型反射裂縫的措施是非常有效的,其鋪設(shè)位置宜在基層頂。
The reflection crack is the most grievous disease in asphalt pavement on a semi - rigid type base course in the northwest area , according to this problem , many measures have been taken to , such as the sma , to adjust the series of material , but the effect is not so good 反射裂縫問題是西北地區(qū)半剛性基層瀝青路面病害中一個(gè)最為嚴(yán)重的問題,對(duì)這一問題已采取了很多措施,例如:使用改性瀝青、調(diào)整材料級(jí)配等,但效果均不理想。
We demonstrated the effect of glasgrid to the reflection cracks , which are produced under the temperature load in asphalt pavement on a semi - rigid type base course . in the paper , from the next three aspects to we demonstrated the argumentation : the theory analyses , the finite element account , experimentation 本文從理論分析、有限元計(jì)算以及實(shí)驗(yàn)三個(gè)方面入手,應(yīng)用斷裂力學(xué)理論論證了玻璃纖維格柵對(duì)半剛性基層瀝青路面在溫度荷載作用下的反射裂縫的作用。
