Method for rapidly detecting compaction density of filled soil
The invention belongs to the technical field of constructional engineering, and particularly relates to a method for rapidly detecting filling compaction density, which comprises the following steps of: driving a novel penetrometer probe into a compacted soil layer according to corresponding requirements, and recording the total penetration number required for driving the novel penetrometer probe into 25cm; meanwhile, the dry density of the position is detected through original detection methods such as a sand filling method and an irrigation method within the range not larger than 1 m around the point, so that a regression equation of the penetration number and the dry density of the soil sample is established, the regression equation is different from direct detection of the compaction degree, the dry density measured through the method is an absolute index, and after the regression equation is established, the density of the soil sample is calculated. After the dry density is directly measured through the penetration number at any position, the dry density can be compared with the maximum dry density obtained through a laboratory, the result of the compactness is finally obtained, and the result obtained through the method is more objective and quicker.
本发明属于建筑工程技术领域，具体涉及一种快速检测填土压实密度的方法，按照相应要求将新型触探仪探头打入压实土层中，记录将其打入25cm所需的总贯入数，同时在该点周围不大于1m的范围内进行灌砂法、灌水法等原有检测方法检测出该位置的干密度，从而建立一个贯入击数与土样干密度的回归方程，与直接检测压实度不同，通过该方法测得的干密度是一个绝对指标，在建立回归方程后，在任一位置直接通过贯入击数测得干密度后，即可与通过试验室求得的最大干密度进行比较，才最终得出压实度这一结果，使用本发明所得到的结果则更为客观，更加快速。
