摘要
工程实践表明对软土地基工后沉降和不均匀沉降有特殊要求的构筑物 ,采用桩网加固地基是一种经济有效的处理方法。由于其作用机理、荷载传递方式是一个复杂的相互作用问题 ,本文运用应力扩散原理估算筋材承受的荷载 ,并由此计算筋材的拉力和割线模量 ,为桩网法设计提供理论依据。
The composite pile-geonets is effective to consolidate soft foundation for some constructions which have special requirement for non-uniform settlement and residual deformation, because its interaction mechanism and loading transmission is a complex problem. In this paper the stress dispersion principle is applied to estimating the loading on geotextile and pile, then the tensile strength and secant modulus are calculated. The result provides a theoretical basis for designing pile-geonets.
