drill sample meaning in Chinese
钻井岩样
钻探岩样
Examples
- The stability of high slopes relies directly on the material strength of rock and soil . the strength parameters used in the design are often obtained from the drilling samples before the slopes are excavated
岩土高边坡的稳定性直接取决于边坡岩土材料的强度，常规边坡设计时往往取边坡开挖前地质勘探所取天然岩土的强度指标作为设计控制值。 - In order to ensure the safety of engineering , it should be careful to use the test result of normal drilling sampling , the pitting sampling , shaft sampling , or double - tubles and thin - wall soil collecting methods should be used
为保证工程安全，对常规钻孔取样试验成果的使用应当慎重，对重要工程宜采用探坑、竖井取样，或采用双筒薄壁取土技术。 - The working stress of the rc compression member in existing structures can be calculated through measuring strain change before and after drilling the hole , determining the compressive strength and elastic modulus of concrete through the drilled sample and combining the calculating results of the finite element method
该方法通过测试钻孔前后孔边应变的变化，利用钻取的芯样推定混凝土的抗压强度和弹性模量，再结合有限元计算分析，得到已建结构中钢筋混凝土受压构件的工作应力。 - Through comparative analysis to the test data of tow sampling methods in drilling hole and sampling method in shaft , it was found out by the author that the drilling sampling method has obvious disturbance and depression to the soil sample , which caused the soil sample ' s dry density to be increased , porosity ratio to be decreased , filtration coefficient to be decreased , and modulus of compression to be increased
笔者通过对钻孔两种方法获取的土样与竖井土样试验数据的对比发现，钻孔取样对土样有明显的扰动和压密作用，造成了土的干密度增大、孔隙比减小、渗透系数降低、压缩模量增大。
