长春市一些高层建筑近年来有些采用一桩一柱的形式。最大荷载达35000KM。在广州、深圳、沈阳持力层选在基岩上,或者是密实园砾、卵石层上。而长春市在8～20米左右,为硬塑～坚硬粘性土。局部地方有白垩纪泥质砂岩风化残积的砾砂含泥质,厚度0.5～0.2米,做为持力层厚度不够。然后是白垩纪风化泥质砂质岩。对于坚硬状态粘性土,从规范中可查到q_p—400～1100KP_a,对于泥质砂页岩,胶结不好,无从查到q_p值。应 Some high-rise buildings in Changchun City in recent years, some using a one-column form. The maximum load of 35000KM. In Guangzhou, Shenzhen, Shenyang holding layer selected in bedrock, or dense garden gravel, pebble layer. The Changchun City in 8 to 20 meters, hard plastic ~ hard clay. Partially local Cretaceous argillaceous sandstone gravel sand muddy, 0.5 ~ 0.2 meters thick, as the holding layer thickness is not enough. Then came Cretaceous weathered shaly sandstone. For the hard state of cohesive soil, from the specification can be found q_p-400 ~ 1100KP_a, for shale shale, cementing is not good, can not be found q_p value. should
