從資料與(yu)結(jie)構(gou)(gou)和功能的(de)(de)(de)本質(zhi)關系上剖(pou)析,選用(yong)柔性、高強(qiang)度(du)(du)的(de)(de)(de)鋼波紋涵(han)管(guan)洞,不(bu)只具有習(xi)慣地基(ji)與(yu)根底變形的(de)(de)(de)能力。板的(de)(de)(de)尺度(du)(du)和厚度(du)(du)為便于(yu)板的(de)(de)(de)加工制造(zao),結(jie)構(gou)(gou)的(de)(de)(de)裝置連接,進步板的(de)(de)(de)制造(zao)精度(du)(du),板材(cai)的(de)(de)(de)尺度(du)(du)宜(yi)習(xi)慣不(bu)同(tong)管(guan)徑的(de)(de)(de)需要,以(yi)構(gou)(gou)成系列化。板的(de)(de)(de)厚度(du)(du)隨結(jie)構(gou)(gou)跨徑的(de)(de)(de)大小改變,板厚可選用(yong)2.5-8mm。

Based on the analysis of the essential relationship between data and structure and function, the selection of flexible and high-strength steel corrugated culvert tunnel not only has the ability to get used to the deformation of foundation and foundation. Size and thickness of plate in order to facilitate the processing and manufacturing of plate, the device connection of structure and improve the manufacturing accuracy of plate, the size of plate should be used to the needs of different pipe diameters to form serialization. The thickness of the plate changes with the size of the structural span, and the plate thickness can be 2.5-8mm.

良(liang)好的焊接(jie)性(xing)能,滿意(yi)波(bo)(bo)紋(wen)管(guan)(guan)在制造進程中的焊接(jie)作業要求(qiu)。管(guan)(guan)頂波(bo)(bo)峰與波(bo)(bo)谷(gu)處(chu)切(qie)向與軸向應力(li)應變隨波(bo)(bo)構(gou)成拉(la)壓替換的改變規則。波(bo)(bo)峰和波(bo)(bo)谷(gu)在管(guan)(guan)頂、管(guan)(guan)底、管(guan)(guan)側(ce)均為應力(li)集中處(chu),各(ge)管(guan)(guan)徑等(deng)(deng)效應力(li)的方(fang)位(wei)與荷載密切(qie)相關(guan);大(da)等(deng)(deng)效應力(li)總體(ti)上隨管(guan)(guan)徑的添(tian)加而添(tian)加;隨著波(bo)(bo)紋(wen)管(guan)(guan)涵洞的壁厚添(tian)加,大(da)等(deng)(deng)效應力(li)呈對數(shu)減(jian)小。

如果涵洞規劃得太小和太接近于地表特別是在露出的當地,并且水流速度緩慢,則在北部地區的冬季簡單凍住,還要阻塞。這能夠得到彌補,方法所以添加涵洞的坡度,選用無底的木制涵洞或在冰冷時節接近時,把涵洞進口端用軟樹技鋪蓋。//hanihanbj.com/
