管桩──桩芯砼组合构件受弯承载力的近似计算

Approximate Calculation on Flexural Capacity of Composite Member with Pipe Pile and Pile Core Concrete

本文基于管桩──桩芯砼组合构件截面的应力分布假设，从理论上探讨并提出了预应力砼管桩──桩芯砼组合构件受弯承载力的近似计算公式，可供工程界设计时参考应用。

Based on the stress distribution assumption of Cross Section,approximate formula for calculating the flexural capacity of the composite member with prestressed concrete pipe pile and pile core concrete is proposed theoretically.
