輕鋼活動房屋地基的要求遠低于傳統的鋼結構。相同的結構單元的基礎上,不應自然基礎的一部分,部分采用人工地基,也不應該超過兩個類和一個大的土壤的性質差異,承重層,當高層建筑的鋼結構基礎底板或地方躺下土壤樁端接近或斜頂面,適當的基礎或樁長度增加,使地基或樁底端全部處于相同的內側，以避免可能產生的不均勻沉降。
The foundation requirement of light steel movable building is far lower than that of traditional steel structure. On the basis of the same structural unit, part of the natural foundation and part of the artificial foundation shall not be adopted, nor more than two categories and one larger soil property difference. Bearing layer, when the pile end of the steel structure foundation slab or place of the high-rise building lies close to or inclined to the top surface, the appropriate foundation or pile length shall be increased, Make the foundation or the bottom of the pile all in the same inner side to avoid possible uneven settlement.
鋼結構施工現場不能避開河流、湖泊和河流的邊緣地段，這些地段在地震中可能產生滑移或地面裂縫。當地震區高層基礎下的地基承載層范圍內的土體可以液化時，輕型鋼結構活動房屋應采取措施土層液化對上部結構的不利影響。
Steel structure construction site can not avoid rivers, lakes and river edge sections, which may produce slip or ground cracks in the earthquake. When the soil within the bearing layer of the foundation under the high-rise foundation in the earthquake area can be liquefied, measures should be taken to eliminate the adverse effects of soil liquefaction on the upper structure of the light steel structure mobile house.
均了地基:土體液化沉降對鋼結構房屋的不利影響，輕鋼活動房屋可因地制宜選擇以下措施之一
All of them eliminate the adverse effect of soil liquefaction settlement on steel structure houses, and one of the following measures can be selected for light steel movable houses according to local conditions
1.顏色的加密方法,如振沖法、沙堆壓實法、強夯法、等,加強基礎時,輕鋼移動房子應該的液化深度的降低界面層,和測量值的標準貫入錘對土層的數量應該大于臨界值的液化土層。
1. The densification method of color, such as vibroflotation, sand pile compaction, dynamic compaction, etc., when strengthening the foundation, the liquefying depth of the light steel mobile house should be treated to reduce the interface layer, and the standard penetration hammer of the measured value should have more liquefying soil layers than the critical value.
2.使用深基礎時，穩定層的深度應不小于基礎底部埋深的500mm。
2. When using deep foundation, the depth of the stable layer shall not be less than 500mm of the buried depth of the foundation bottom.
3.鋼活動房鋼結構工程施工中采用樁基礎時，應根據樁的承載力計算確定樁頂液化深度以下穩定土層的長度。
3. When pile foundation is used in the construction of steel structure of steel mobile house, the length of stable soil layer below the liquefaction depth of pile top shall be determined according to the calculation of pile bearing capacity.
