绵阳冰水沉积粘土展布于四川省涪江、安昌河两岸的侵蚀堆积地形上,在地貌上属于第三级和第三级以上的高级阶地,该阶地的特点是不连续,呈基座式,出露较为广泛,面积一般在数至十数平方公里,高出当地河面20～90米以上,海拔多在500～550米以上,是城市和工业建筑物基础的主要持力层。由于建设的需要,我院自六十年代初期便对这种地基土的特性进行了研究,现将成果介绍如下。
Mianyang ice-water sedimentary clay spreads on the eroded and accumulating landforms on the banks of the Lancang River and Anchang River in Sichuan Province. It belongs to the third-level and third-level high-grade terraces in geomorphology. The terrace is characterized by discontinuous and pedestal-type. Exposed, the exposure is more extensive, the area is generally in the number of tens of square kilometers, higher than the local river surface 20 to 90 meters above sea level, more than 500 to 550 meters above sea level, is the city and industrial buildings based on the main bearing layer. Due to the need of construction, the characteristics of this foundation soil have been studied in the early sixties of our institute. The results are presented below.
