一、前言板桩计算主要在于土压力的计算和板桩内力的计算。土压力和板桩内力的计算,国内外有各种不同的计算方法,由于计算方法的不同其结果也不同。我国通常用弹性线法计算板桩内力,土的指标根据经验多用固结快剪指标,而板桩结构的破坏多发生在施工过程中,因此,当为软粘土时、特别是回填软粘土时,用十字板或无侧限指标是比较符合实际情况的。下面用日本《港湾设施技术标准》中的方法、就软粘土的土压力及板桩内力的计算做一
First, foreword Sheet pile calculation mainly lies in the calculation of earth pressure and pile internal force calculation. The calculation of earth pressure and internal force of sheet piles has various calculation methods at home and abroad. The results are also different due to different calculation methods. In our country, the internal force of sheet piles is usually calculated by elastic line method. The indexes of soil are mostly used to consolidate the quick-shear indexes based on experience. However, the damage of sheet piles structure occurs in the process of construction. Therefore, when it is soft clay, , With the cross plate or unconfined index is more in line with the actual situation. Below with the Japanese “harbor facilities technical standards” in the method of soft clay soil pressure and pile internal force calculation to do a
