土体渗气性原位测试装置初探
Primary exploration of a Test device for permeability of pore air of unsaturated soils
土的渗气性是其基本性质之一，准确测定其大小对于工程设计具有重要意义。本文提出了一种新型的原位测试土体渗气性的仪器设备，在现场就能够快速测定土体的渗气系数，并且减小了土体的扰动，从而减小实验误差，得到真实反映土体渗气性能的测试结果，为工程的设计和施工打下良好的基础。
Permeability of pore air is one of the basic characters of unsaturated soil.In engineering design,it's important to measure it accurately. This text bring up a new kind of device that can test permeability of pore air in situ. It has several advantages,including less time on experiment and decrease the disturbance of the soil etc.The experiment error will be reduced,experiment result representative the permeability of pore air faithfully,and grounded well in engineering design.
