摘要
木桩复合地基能提高软弱地基的承载能力。杨庄闸是江苏现存最早的水工建筑物,已投入使用70多年,工程主体结构已呈现明显的老化、病害等现象,对其进行保护性加固和修复十分必要。为合理有效地进行工程的加固修复,采用现场取样的方法,对底板下的木桩材料力学性能进行试验研究。试验主要测试木桩材料的抗压强度、抗压弹性模量、抗弯强度和抗弯弹性模量。试验结果为工程的加固修复设计与施工提供了依据。
The complex groundwork with timber pile has advanced carrying capacity. Yangzhuang floodgate has been worked for more than seventy years and has been damaged in the structure. So, it is necessary to reinforce the structure. In order to carry out this work, the material me- chanical properties of specimen from in suit timber pile are tested. The compression strength, compression elastic modulus, bending strength, and bending elastic modulus are measured. The testing results can be used in design and building of the structural reinforcement.
