本文介绍一种新型支挡结构物——具有拉杆的锚固桩的计算方法。计算公式的建立是根据差分原理,并借助于材料力学和矩阵代数的基本知识完成的,公式简单明瞭,便于掌握。它不仅考虑了桩与地基的相互作用,而且也考虑了桩与拉杆的相互作用,较为合理。 作者将计算公式作了推广、延伸,证明此方法不仅适用于具有拉杆的锚固桩的计算,而且也适用于无拉杆的情况,对于后一情况,计算更为简单。作者对港口工程中的单锚板桩墙也采用本方法进行了计算,并与现行方法作了分析比较,认为本文所介绍的方法也同样适用于港口工程中的板桩墙的计算。
This paper introduces a new type of retaining structure—the calculation method of anchoring piles with tie rods. The establishment of the calculation formula is based on the principle of difference, and is accomplished by the basic knowledge of material mechanics and matrix algebra. The formula is simple and straightforward and easy to grasp. It not only considers the interaction between the pile and the foundation, but also considers the interaction between the pile and the tie rod, which is reasonable. The author has extended and extended the calculation formula to prove that this method is not only applicable to the calculation of anchoring piles with tie rods, but also applicable to the case without tie rods. For the latter case, the calculation is simpler. The author also calculated the single-anchor pile wall in the port engineering by this method, and analyzed and compared with the current method. He believes that the method described in this paper is also applicable to the calculation of sheet pile wall in port engineering.
