| 摘 要： | 应用数学和力学方法,从土压平衡盾构的掘削工作机理入手,研究顶进推力的计算方法及其影响因素。开展土压平衡盾构的掘削模型试验,研究在不同埋深、不同刀盘开口率以及不同土性时的千斤顶顶进推力的变化规律,并对前述理论研究成果加以验证。结合地铁隧道工程实例,应用推导的推力计算公式预测盾构推进过程中的顶进推力,取得了较为满意的结果。

| Abstract: | The reasonable calculation method of thrust force and its influencing factors were studied by applying mathematics and mechanics based on the working mechanism of EPB shield machine.Model experiments on thrust force during tunnel excavation with EPB shield machine under different conditions of burying depth,cutter opening rate and soil property were carried out.The aforementioned theoretical results were also verified.Combining with a subway tunneling case,the derived formula was used to forecast the values of thrust force in the course of shield tunneling,and satisfactory results were achieved. |
