In major cities of Vietnam, such as Hanoi and Ho Chi Minh city, there are many facilities for the construction of underground spaces, such as the basement of high-rise buildings, underground parking, and subway ... Vietnamese geological characteristics of weak water-saturated soils are represented by clay soils and loose Sands are often organic, in some places including layers of silt and peat, as well as high groundwater levels, therefore, when the construction of underground structures leading to precipitation of the soil surface affecting adjacent buildings. The article presents the content of the method of constructing a model of the sediment of the soil surface around the deep pits when the load of the neighbors of the building and the distance from the pit to the building program Plaxis 2D. Consider the case of a deep pit with a depth of Hk = 8 m using the top-down method, the ground load varies q = (10-50) kN / m and the distance to the pit is L = (0.5-1.5)Hk. Based on the results obtained, using Matlab software, simulate the subsidence of the soil surface around a deep pit.
