控制粉煤灰密实度以替代砂类土的原位测试

本文是一例研究粉煤灰替代排水砂沟中以黄砂为材料的原位试验。通过建立静力触探比贯入阻力与干容重的相关关系,找出达到设计要求的7.5 KN/m干容重的最佳夯实击数(振密遍数),从而有效地控制了粉煤灰的密实度。

FLY ASH FROM COAL AS A SUBSTITUTE OF SAND IN CONTROLLING ITS COMPACTNESS IN SITU

This paper studies the possibility that sand is substituted in situ by fly ash in sand dicths. Through setting up the connection between the specific penetration of CPT and the wieght,the optium compactive number of dynamic consolidation of 7.5 KN/m~3 for dry unit can be found in order to satisfy the design demand and to control effectively compactness of fly ash of coal.
