摘要
分析了顶管顶力的组成及其影响因素,从理论上推导了顶力计算公式,并给出了考虑注浆减摩的经验计算公式同时提出了顶力计算应注意的问题。通过分析工程实例,验证了计算公式的合理性和适用性。
The article analyzes the constitution and the affected factors of jacking forces. The calculation formulas for jacking forces are presented in theory, and the experience formulas, which take account of grouting for reducing the friction force, are showed in this paper. Meanwhile, it points out the key points that should be paid attention to when calculating jacking forces. By analyzing an engineering case, the reasonableness and the adaptability of calculation formulas were verified.
