tip resistance meaning in Chinese
桩端阻力
舂端阻力
Examples
- Tip resistance pile
桩端抗力 - Today , cast - in - situ piles are more widely used in deep foundation engineering because of their many advantages , such as better adaptability to various ground condition , providing enormous bearing capacity by a single pile and smaller dosage of reinforcing steel bar . but , their own disadvantages , such as sediment under tip , clay slurry around pile , friction and tip resistance disagreement and initial ground stress freeing , limited their bearing capacity , lowered the utilization ratio of material and increased the settlement
灌注桩，因其对地层适应性强、能提供较大的单桩承载力、钢筋用量少等优点，在目前深基础工程中得到了极为广泛的应用。但是，灌注桩的固有缺陷，诸如孔底虚土；孔壁泥浆；端阻、侧阻发挥不同步；钻孔后原地应力释放等，限制了其承载力的发挥，使得材料利用率不高，沉降较大。 - In this section the author analyses the rules of the pile ultimate tip resistance and the shaft friction resistance distribution and their exertion of cast - in - place socketed piles instrumented with strainometers in soft muddy rock . the second aspect of the paper is the analysis on the current rock pile vertical bearing capacity in the four standards gb50007 - 2002 , tb 10002 . 5 - 99 , jtj024 - 85 and jgj94 - 94 , then the design method with correlated formula of socketed piles in xigeda - mudstone is given . at the end of this paper , based on the research of pressure grouting technique in recent years , and combined with in - site test result , this paper puts forward the design and calculation method to grouted pile in xigeda - mudstone and the principle of choosing grouting parameters , which provid es experiences for applying this technique and further studying
本论文结合省级科研项目“西攀高速公路昔格达组泥岩层中钻孔桩提高承载力的研究” ，所做的研究工作主要在以下三个方面：一是根据8根桩身内埋设量测元件试桩的单桩竖向静载荷试验资料，分析了各试验桩特别是常规冲孔灌注嵌岩桩在昔格达泥岩中的轴向力、侧摩阻和桩端阻力的分布和发挥规律；二是在讨论现行规范对嵌岩桩承载力的计算公式的基础上，探讨了在昔格达泥岩层中的冲孔灌注嵌岩桩的侧摩阻和端阻的计算方法，并推荐了相应的计算公式；最后，在吸取近年来对灌注桩后注浆技术研究成果的基础上，结合现场试验研究结果，分析了该项技术在昔格达岩层中的应用效果，提出了相应的参数选取，从而为压力灌浆技术的工程应用和进一步研究提供经验，并为今后在该地层中合理选用桩型以及指导施工提供了依据。
