weather layer meaning in Chinese
风化层
Examples
- Such low velocities are usually seen only near the surface in a zone called the weathered layer or the low-velocity layer .
这样低的速度通常只在地表附近称为风化层或低速层的地带中见到。 - The ground base of the newly added chute in 4 tailings reservoir at dexing copper mine is characterised by thick weathered layer , loose structure , fractured zone and landslip mass accumulation . as a result , the ground has a great subsidence and inefficient carrying capacity . in view of this , the grouting technology was adopted to reinforce the chute ground base . the on - site testing shows that the subsidence of the chute has been efficiently controlled and the carrying capacity of the ground base improved so that the stability requirement has been met
浅地表赋存小矿体开采是矿山生产的有效补充,通过对潘洛铁矿洛阳矿区浅部零星小矿体开采现状分析,从加强开采技术,生产管理角度提出了自己看法.主要应加强小矿体的勘查工作,以及开采的总体规划,统筹管理,实现浅地表赋存小矿体的安全高效回采 - The ground base of the newly added chute in 4 tailings reservoir at dexing copper mine is characterised by thick weathered layer , loose structure , fractured zone and landslip mass accumulation . as a result , the ground has a great subsidence and inefficient carrying capacity . in view of this , the grouting technology was adopted to reinforce the chute ground base . the on - site testing shows that the subsidence of the chute has been efficiently controlled and the carrying capacity of the ground base improved so that the stability requirement has been met
潘洛铁矿主要使用的采矿方法是浅眼落矿的全面法和留矿全面法. 23矿体160m以上矿段上部为氧化矿和风化岩层,形成挤压爆破和松散岩石覆盖下的放矿条件.介绍了无底柱分段崩落法在该矿体开采中的应用.实际使用获得的各项技术经济指标还比较理想 - The ground base of the newly added chute in 4 tailings reservoir at dexing copper mine is characterised by thick weathered layer , loose structure , fractured zone and landslip mass accumulation . as a result , the ground has a great subsidence and inefficient carrying capacity . in view of this , the grouting technology was adopted to reinforce the chute ground base . the on - site testing shows that the subsidence of the chute has been efficiently controlled and the carrying capacity of the ground base improved so that the stability requirement has been met
针对金山店铁矿余华寺采区的开采条件:拥有独立的开拓系统、产量不大、装备水平不高、矿岩松软破碎、地压大等,进行了无底柱分段崩落法采场结构参数的优化研究.通过室内物理、数值模拟和现场工业试验,探索出合理的分段高度、进路间距、放矿步距等参数,以求达到技术上可行经济上最优.该研究成果在矿山的应用中取得了可观的经济效益,为其它类似的中小型冶金矿山探索出一条提高经济效益的途径 - The landslide feature of the expansive soil is analyzed . the stability of the expansive soil slope is largely dependent on the weal link . the slope stability analysis of the expansive soil should consider the weathering , so all the analysis should be classified to two different types : weathered layer and non - weathered layer
对膨胀土路堑边坡滑坡特点进行了分析，指出膨胀土边坡主要受软弱结构面控制，提出了膨胀土边坡稳定分析应分为风化层和深层未风化层的方法，并建议了不同部位土的抗剪强度指标取值方法。
