疏浚淤泥废弃泡沫塑料轻质土的力学特性研究

Study on mechanical property of stabilized light soil mixed by dredged material

为了处理我国港口航道工程的维护和建设中产生的大量疏浚淤泥,以疏浚淤泥为原料土,添加水泥及废弃泡沫塑料,开发出了具有较高技术经济效益的新型土工材料—疏浚淤泥废弃泡沫塑料轻质土。对某一特定配方的试样进行了无侧限抗压强度试验、各向等压压缩试验及三轴试验,并对疏浚淤泥废弃泡沫塑料轻质土的压缩、剪切特性进行了研究。

In order to dispose a great quantity of dredged material from ports and waterway maintenance and construction, a new type of geotechnic material-stabilized light soil with expanded polystyrene was developed. The shear and compression property of the stabilized light soil have been studied by the unconfined compressive strength test, isotropic compressive test, consolidated drained triaxial compression test and consolidated undrained triaxial compression test.
