Foundation processing method for vibration isolation of filtering cushion layer
The invention discloses a foundation processing method for vibration isolation of a filtering cushion layer, and relates to the technical field of civil engineering. The method comprises the followingsteps that a soft soil layer in a certain depth below a foundation is dug for laying the cushion layer, the cushion layer comprises N thin layers, the material of each thin layer is one of sand, gravel, plain soil and gray soil, the materials of the adjacent thin layers are different, the thickness of each thin layer is the same, and the thickness of each thin layer is 0.3-0.6 m; firstly, the material of each thin layer is determined, and then the thickness and the compactness of each thin layer are adjusted according to the self-vibration period of an upper building, so that the amplitude response value of the surface meets the design requirement; the filling and compaction of each thin layer are then performed, and the preset compactness and thickness of each thin layer are achieved; and after each thin layer is filled and compacted, the filling soil is filled above the cushion layer. The method is reasonable in structure, simple in construction and low in manufacturing cost, the shock absorption and disaster prevention performance of the cushion layer and the foundation can be effectively improved, and a traditional construction method is not changed.
本发明公开一种滤波型垫层隔震的地基处理方法，涉及土木工程技术领域，包括以下步骤：将基础下一定深度内的软弱土层挖去,用于铺设垫层，垫层包括N个薄层，各个薄层的材料为砂、碎石、素土和灰土中的一种，相邻的薄层的材料不同，各个薄层的厚度相同；薄层的厚度为0.3‑0.6m，首先确定各个薄层的材料，再根据上部建筑物的自振周期，通过调整各个薄层的厚度和密实度，使得地表的振幅响应值满足设计需求；然后进行各个薄层的填筑和压实，达到各个薄层预定的密实度和厚度；填筑并压实各个薄层之后，在垫层上方填入回填土。该方法结构合理，施工简单，造价低廉，可有效提高垫层和基础的减震防灾性能，并且不改变传统施工方法。
