近年来,顶管施工技术在中国得到迅速发展,并广泛应用于给排水管道工程,但顶管施工中土体的扰动机理及土体性状的变化有待深入研究与探讨。在前人的基础上,研究顶管施工引起土体扰动的机理,提出更加准确的土体扰动分区图。对某顶管工程进行现场监测,内容包括地面变形、深层土体移动、孔隙水压力、土压力、地下水位及顶管施工现场记录。测试结果土体扰动受土质条件、施工技术和现场控制程度的影响,其中现场控制程度的影响最大. In recent years, the pipe jacking technology has been rapidly developed in China and widely used in the water supply and drainage pipelines. However, the disturbance mechanism of the pipe jacking and the change of the soil properties need further study and discussion. On the basis of the predecessors, this paper studies the mechanism of soil disturbance caused by pipe jacking and proposes a more accurate map of soil disturbance. On-site monitoring of a pipe jacking project, including the deformation of the ground, the movement of deep soil, pore water pressure, earth pressure, groundwater level and pipe jacking site record. Test results Soil disturbance is affected by soil conditions, construction technology and site control level, of which the degree of site control has the greatest impact.
