Resonant frequency-based rock-filled roadbed rapid compaction construction technology
The invention discloses a rock-filled roadbed rapid compaction construction process based on resonant frequency, which comprises the following steps: (1) selecting a section of roadbed from a rock-filled roadbed to be compacted as a test object, carrying out vibration monitoring on a vibrating wheel on the test object through a field frequency sweep test, and determining a sensitive frequency interval of the roadbed; (2) selecting a plurality of frequency values in the sensitive frequency interval, and arranging the frequency values from small to large; then the roadbed is rolled under the frequency values, porosity detection is carried out after rolling of each frequency is finished, and each frequency and the corresponding roadbed porosity are recorded and recorded as a reference group; (3) selecting another section of roadbed from the to-be-compacted rock-filled roadbed as a test object, rolling the roadbed for the first time, detecting the porosity and the dynamic deformation modulus after rolling for the first time, and recording the porosity and the dynamic deformation modulus as A1 and B1; and so on, until the porosity of the roadbed reaches or is superior to a required value. Rapid construction of the rock-filled roadbed is achieved, and the construction efficiency is remarkably improved while good construction quality is ensured.
本发明公开一种基于共振频率的填石路基快速压实施工工艺，包括步骤：（1）在待压实的填石路基中选取一段路基作为测试对象，通过现场扫频试验对该测试对象进行振动轮振动监测，确定路基的敏感频率区间。（2）在敏感频率区间取若干频率值，从小到大排列。然后对路基进行这些频率值下的碾压，每个频率碾压结束后进行孔隙率检测，记录各个频率及其对应的路基孔隙率，记为基准组。（3）在所述待压实的填石路基中选取另一段路基作为测试对象，对其进行第一遍碾压，结束后检测孔隙率和动态变形模量检测，并记为A1、B1。以此类推，直至路基的孔隙率达到或优于要求的值。本发明实现填石路基的快速施工，在确保良好施工质量的同时显著提高了施工效率。
