开挖断面 meaning in Chinese
excavated section
Examples
- Cylinder excavation section
筒形开挖断面 - Therefore dredged section ' s wide - deep radio will be a good value adopted as well
因此，开挖断面宽深比也同样存在一个较佳的取值范围。 - The experimental research shows that the more wide - shallow the dredged section size is , the bigger the back - deposition ratio will be . but when the dredged section is over narrow - deep , the back - deposition ratio will be increasing with decreasing of wide - deep radio
试验研究表明：开挖断面愈宽浅，开挖段回淤比越大，但过于窄深时，回淤比反随宽深比减小而增大。 - Under the chosen conditions of testing discharge - sediment and scheme of dredged section , the effect of dredging river for deposition reduction will be considered better when the dredged section ' s wide deep radio is - ^ b ~ nlhn with 6 ~ 9 and dredged section area is about 250 ~ 300m2
在选定的试验水沙条件和挖河断面方案下，认为开挖断面面积在250 300m ‘左右，断面宽深比vb 。 m在6 9之间挖河减淤效果11 。 - Daping tunnel in chongqing light - rail construction is located in downtown chongqing , where there has a dense population as well as numerous buildings . daping station tunnel enjoys a span in the clear of 19 . 8 meters , whereas its excavation span and area are 26 . 3 meters and 430 . 3 square meters respectively in the context of mere 4 - meter overburden and with a surrounding rock category of iii
重庆轻轨大坪车站隧道位于重庆主城区内，地面上人口密集，建筑物林立，大坪车站隧道净跨19 . 8米，开挖宽度26 . 3米，开挖断面430 . 3m ~ 2 ，覆盖层厚仅4米，围岩类别为类围岩。
