针对桩承式加筋体变形和受力的理论计算研究,从分布荷载和计算原理两个方面总结了国内外桩承式加筋体的理论计算方法,并对各种方法的特点进行了分析。分析表明,反三角形分布的荷载形式比均布载和三角形荷载更加合理;二维计算中的德国规范法相对于抛物线法和圆弧线法更能准确描述加筋体的变形,但无法反映拉力沿长度方向的变化;三维计算的薄板理论方法能够分析如土拱格栅的网格状加筋体,但不适用土工膜等膜材类加筋体。
Aiming at the theoretical calculation research on the deformation and stress of pile-supported reinforced body, the theoretical calculation methods of pile-supported reinforced body at home and abroad are summarized from two aspects of distributed load and calculation principle, and the characteristics of various methods are analyzed . The analysis shows that the inverse triangular distribution is more reasonable than the uniform distribution and triangular loads. The German standard method in two-dimensional calculation can describe the deformation of the reinforced body more accurately than the parabola method and the circular arc method. However, Length of the change; three-dimensional calculation of the thin plate theory method can analyze such as soil arch grid grid reinforcement, but does not apply geomembrane and other membrane reinforcement.
