谈新旧建筑物的基础支护

为了提高土地的利用率，创造良好的经济效益和社会效益，须采取支护措施，在保证不影响邻近建筑物基础稳定的条件下，缩小新旧建筑物基础边缘的距离。通过分析，结合工程实例证明，当新旧建筑物基础底面标高高差H与其边缘的最小距离L之比小于或等于0．5时，能保证建筑物的安全和正常使用。

Effective utilizing land resources through well foundation supporting of new and old buildings

In order to enhance the land utilization ratio and to create good economic benefit and social benefit some effective supporting measures must be adopted under the conditions of not influencing the stabilization of neighbor buildings to reduce the distance of foundations of new and old buildings. Through the analysis and study the conclusion is verified that when the ratio of the difference of bottom elevation as H and the minimum distance of borders as Lless than or equal to0.5 the safety and normal operation can be ensured.
