Shallow foundation structure suitable for soft soil foundation
The invention discloses a shallow foundation structure suitable for a soft soil foundation, which comprises a base body, and the base body is pre-buried in soft soil and is used for bearing the load of a structure; the base body is configured in the mode that the self weight of the base body is matched with a preset value, and the preset value is the difference value between the weight of soft soil in the space occupied by the base body and the load of the structure. Due to the fact that the base body is embedded in the soft soil, the base body is equal to the excavated soft soil in volume, on the basis, the sum of the base body and the base top dead load borne by the base body is equal to the weight of the removed soft soil, the stress of the bottom face of the shallow foundation structure is equal to that of the original-state soft soil, and the soft soil does not need to build a new balance state again. Therefore, the uncertainty in the process of rebuilding the balance of the soft soil is avoided; meanwhile, the key point of the embodiment of the invention is to calculate and design the weight and the volume of the base body, and only the foundation pit needs to be excavated and the base body needs to be buried during construction, so that the method has the characteristics of short construction period and low engineering cost.
本发明公开了一种适用于软土地基的浅基础结构，包括基体，所述基体预埋在软土中，用于承受构造物的荷载；所述基体被配置为所述基体的自重与预设值相匹配，所述预设值为所述基体所占空间内的软土的重量和所述构造物的荷载的差值。由于基体预埋在软土中，因此基体与挖出的软土的体积相等，在此基础上，将基体设置基体与其承载的基顶恒载之和等于去除的软土的重量，使得浅基础结构底面的应力就于原状软土相等，软土就无须重新建立新的平衡状态。因而避免了软土重新建立平衡的过程中的不确定性；同时，本发明实施例的重点在于计算并设计基体的重量和体积，施工时仅需挖开基坑、埋设基体，因此具有工期短、工程成本费用低的特点。
