基于实际情况的需要，研究碾压混凝土坝基础长间歇垫层的温度应力影响因素，对于温控防裂具有重要实用价值。
Based on the actual needs of the situation to study the thermal stress factor for a foundation during long intermittence of roller compacted concrete dam is the great scientific value.
在碾压混凝土坝施工过程中，有时因为灌浆和导流的需要，基岩上浇筑完基础垫层后长时间停歇，即形成基础垫层长间歇。
In RCC dam construction project, sometimes because of the need for grouting and river diversion, the thin concrete block during long intermittence would be caused after a long idle time.
