摘要:
针对兰州某小区商住楼已形成不均匀沉降的地基,根据场地施工条件、地基条件和建筑物的结构特征, 对该工程地基选择了高压旋喷注浆法进行加固,加固结果表明:加固前及加固初期地基沉降速率较大,加固施工 完成后沉降速率变小,加固完成两个月后沉降稳定,加固效果良好。通过该工程实践表明:高压旋喷注浆法在复 杂地基中对既有建筑物的加固处理虽然是可行的,但同时必须根据地基土的特点采取相应的切实可行的技术措 施,才能使地基加固处理达到预期的效果。其加固原理既有旋喷桩的托换加固之功效,又有静压注浆加固之 作用。
Abstract:
The community buildings have sub-grades that sinks asymmetrically because it consists of much break- ing sandstones. Considering the given situation of the engineering condition, sub-grade and structure characteris- tic of the buildings, the sub-grade is reinforced with the high pressure jet grouting method, and some special measurements are carried out to ensure the technology of making holes,infusing mud and construction procedure. Before and during the reinforcement, the sub-grade sinks quickly. However, after the reinforcement, the velocity of settlement becomes slower. And two months later, the sub-grade becomes steady . The reinforcement engi- neering confirms that the high pressure jet grouting method can be used effectively to reinforce complex founda- tions of the existing buildings, but to achieve the anticipant result, practicable technique should also be taken ac- cording to the characteristics of the foundation soil at the same time. The principle of the reinforcement has the function of the replaced reinforcement of the revolving and spurting column as well as the function of the static pressure afflux, it can be taken as the lesson for other engineering.
