深基坑桩锚支护的设计要点

桩锚支护体系是深基坑支护体系最常用的形式之一，其土压力分布按库伦(或朗肯)理论确定，护壁桩采用等值梁法进行计算，介绍了桩锚支护体系的设计要点，包括土压力的计算、悬臂桩的计算、单层锚杆护壁桩的计算、多层锚杆护壁桩的计算等内容。

Design Points of Pile-anchor Supporting in Deep Foundation Ditch

The pile-anchor supporting system is one of the common forms of the supporting systems in deep foundation pitch, the distribution of its earth pres sure is determined by Coulomb's (or Rankine's) earth pressure theory, and the ca lculation of the wall pile is made with the equivalent beam method. This paper i ntroduces the design points of the pile-anchor supporting system, including the calculation of the earth pressure, the calculation of the cantilever pile, the calculation of the single-layer anchor wall pile, and multi-layer anchor wall pile, etc.
