污泥含量对气泡混合轻质土性能的影响研究

为了探讨污泥的基本性质及气泡混合轻质土中污泥含量对其性能的影响，采用干密度及颗粒比试验对污泥基本性质进行评价，结果显示:污泥是一种轻质原料土，其颗粒比有助于轻质土性能的提高。采用干密度、流动度、吸水率、抗压强度试验研究轻质土中污泥含量对其性能的影响，结果表明:气泡混合轻质土湿容重等级为W8；其流动度18 cm±2 cm、气泡的闭合度、抗压强度（1.118~1.806 MPa）及竖向位移（2.86~4.04 mm）均满足实际工程的要求。

Research on Influence of the Performance of Sludge Content to Bubble Mix Light Soil

To discuss the basic property of sludge and the influence of sludge content in bubble mix light soil on its performance, the dry density and particle proportion test were adopted to evaluate basic property of sludge. The results show that the sludge is a light raw soil and its particle proportion can improve the performance of light soil property. Dry density, fluidity, water absorption and compression test were performed to study the influence of sludge content in light soil on its performance. The results show that the wet density grade of bubble mix light soil is W8; its fluidity is 18 cm±2 cm, the bubble closure, compressive strength (1.118~1.806 MPa) and vertical displacement (2.86~4.04 mm) actual requirements of project.
