工程板房地基的处理方法

来源:http://www.lxcaigang.com 日期:2020-04-27 发布人:admin
轻钢活动房屋地基的要求远低于传统的钢结构。相同的结构单元的基础上,不应自然基础的一部分,部分采用人工地基,也不应该超过两个类和一个大的土壤的性质差异,承重层,当高层建筑的钢结构基础底板或地方躺下土壤桩端接近或斜顶面,适当的基础或桩长度增加,使地基或桩底端全部处于相同的内侧,以避免可能产生的不均匀沉降。

  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.

  钢结构施工现场不能避开河流、湖泊和河流的边缘地段,这些地段在地震中可能产生滑移或地面裂缝。当地震区高层基础下的地基承载层范围内的土体可以液化时,轻型钢结构活动房屋应采取措施消除土层液化对上部结构的不利影响。
  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.
  均消除了地基:土体液化沉降对钢结构房屋的不利影响,轻钢活动房屋可因地制宜选择以下措施之一
  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.颜色的加密方法,如振冲法、沙堆压实法、强夯法、等,加强基础时,轻钢移动房子应该治疗的液化深度的降低界面层,和测量值的标准贯入锤对土层的数量应该大于临界值的液化土层。
  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.使用深基础时,稳定层的深度应不小于基础底部埋深的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.钢活动房钢结构工程施工中采用桩基础时,应根据桩的承载力计算确定桩顶液化深度以下稳定土层的长度。
  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.
