The horizontal coefficient of consolidation is the most important parameter for designing the improvement of soil soft by prefabricated vertical drains (PVDs) combined with surcharge and vacuum preloading. This paper presents the experimental study on the horizontal coefficient of consolidation ( c   h  ) of some soft soils distributed in Vietnam. The c   h  value was determined by the laboratory test and CPTu dissipation test. The laboratory tests included the Rowe consolidation cell test and constant rate of strain consolidation with radial drainage test. Two types of consolidation laboratory tests were performed. The experimental results indicated that the c   h  value is always larger than the vertical coefficient of consolidation of soil (    c    v    ). The ratio of c   h  /    c    v    depends on the consolidated pressure, type of soil, and the anisotropy of soil. The ratio of c   h  /    c    v    is different in different types of soft soil in Vietnam. In the normally consolidated state, the c   h  /    c    v    ratio ranges from 1.35 to 10.59. It was necessary to choose the c   h  value at the consolidated stress level for calculating the PVD spacing.
