| 摘 要： | 软土地层中的浅层气是一种矿产资源,也是一种地质灾害源。上海地区随着地下工程广泛兴建,其灾害评估为人们所重视。浅层气源于mQ42淤泥质粘性土生气层中有机质的分解作用,储存于该地层上覆、下伏及中部所夹的粉细砂、贝壳砂等储气层中。在上海地区,浅层气的灾害影响将越来越小。

| Abstract: | The shallow layered natural gas contained in soft strata is either mineral resource or geological hazard. Now the hazard appreciation is paid attention extensively in Shanghai. The shallow layered gas geneted by organic decomposition in silty clayed strata (gasgenic strata) and reserved in sandy strata (gas reservoir) layered near silty clayed strata. In Shanghai region ,the hazards influence will decrease more and more. |
