摘要:

为了研究含气土的固结渗透特性,在前人的基础上研制了固结-渗透-注气联合试验装置.该装置克服了水气分离和密封两大难题,具有结构简单、应用范围广等特点.为了检验该试验装置的可行性,利用该装置进行饱和土的固结和渗透试验,表明该装置与传统装置的试验结果具有较好的一致性.利用该装置进行注气试验,虽然目前注气试验尚无其他同类试验资料作对比,但试验的结果规律性较好,由此可以判断所研制的试验装置是合理可行的.研制的试验装置有望在研究含气土的固结渗透特性方面发挥作用,也可以用于研究气泡在土体中的运移特性.

Abstract:

A newly multifunction device was proposed to investigate consolidation and permeability of gassy soils, coupled with test of consolidation, permeability and gas-injection experiment. The device was easily assembled to accomodate a wide variety of the tests without limitation or drawback of water-gas separation and sealing. Test reliability of the device was validated by the test implemented in consolidation and permeability measurement of saturated soils, which indicated that the new device experimental results accorded with the conventional device. For the gas-injection experiments, though with little data available from other experiments regarding the comparison, scientifically sound data with regularity was obtained, proving feasible in application of the device. Technically as a fresh approach to investigate both the consolidation and permeability of gassy soils, the device in this special issue may be applied to the research of bubbles transport process in soils.
