摘　　要：本文以天津临港经济区某地基处理工程为实例,介绍了处理软土地基施工过程中排水板打设采用长、短板相结合的施工工艺,并对采用该工艺所起到的加固效果进行了分析。认为采用该方法不仅能够节省造价,缩短工期,还能有效地改善场地地质条件,增强土体的抗剪强度,特别是对新吹填层土体的加固效果明显。排水板长、短板打设相结合的施工方法在天津临港经济区真空预压中的成功应用,对于其他地区的类似工程具有指导意义。Based on one foundation improvement project of Tianjin port economic zone, an introduction has been given to the construction technologies of applying long and short draining boards in soft base improvement, and its reinforcing effect has been analyzed. This analysis results show that the above method can reduces the project cost, shorten the construction period, effectively improve local geological conditions, and increase the shear strength of soil body. In addition, the method is of remarkable reinforcing effect on new dredger-filled soil layer. The combination of long and short draining boards is applied successfully in soft base improvement, which serves as a significant guidance for other similar projects.
