| 摘 要： | 浅气层在上海软土层中广泛分布,浅气层中的土,属于含高压孔隙气的非饱和土.本文主要介绍了含气砂土层,在高压孔隙气释放后,发生固结变形的室内模拟试验,分析总结了试验所得规律,并在此基础上探讨了浅气层的工程危害性机理,最后进一步提出了相应的防治措施.

EXPERIMENTAL STUDY ON CONSOLIDATION LAW OF UNSATURATED SOIL CONTAINING HIGH-PRESSURE GAS |
| |
| Abstract: | The marshgas?containing layers are popularly in the Shanghai area. The soil in the marshgas?containing layer are unsatu rated soil containing high?pressure gas. The data obtained from the tests are analyzed. A consolidation law of the unsaturated soil containing high?pressure gas as the gas drained out slowly is obtained. At same time, some empirical formula for the stress?strain and strain?time are obtained. The test result has shown that the ptastic deformation is occurred first than followed the elastic deformation. The mechanism of engineering disaster caused by the unsaturated soil layer containing high?pressuye marshgas is discussed too. Furthermore, some prevention measures are proposed. |
