Treatment method for preventing sinking of foundation and terrace of gas collecting station in collapsible loess area

The invention discloses a treatment method for preventing sinking of a foundation and terrace of a gas collecting station in a collapsible loess area. The treatment method comprises the following steps that (1) the collapse lower-limit depth is judged according to collapse amount calculation and self-weight collapse amount calculation, and a proper foundation treatment method is selected; (2) foundation surrounding and water apron construction is conducted; and (3) an overall drainage system is constructed. Through the set of complete construction treatment method for preventing sinking of thefoundation and the terrace of the gas collecting station in the collapsible loess area, harm of foundation collapse to all buildings, equipment and the like is prevented. 本发明公开了种湿陷性黄土地区防范集气场站地基及地坪下沉处理方法，包括以下步骤：（1）根据湿陷量计算、自重湿陷量计算判断湿陷下限深度，并选用合适的地基处理方法；（2）基础周边及散水施工；（3）整体排水系统的建设。本发明通过套完整的防范湿陷性黄土地区集气场站地基、地坪下沉的施工处理方法，防止地基湿陷对各建筑、设备等产生危害。
