Method for obtaining roadbed soil compaction degree under compaction effect
The invention discloses a method for obtaining the roadbed soil compaction degree under a compaction action. The method comprises the following steps that S1, indoor experiment and numerical simulation are conducted, specifically, firstly roadbed soil is sampled, the compaction degree characteristics and the elasticity modulus are detected, and a relationship between the roadbed soil compaction degree and the elasticity modulus are established; S2, an outdoor road to be compacted is measured, specifically, an area in which the compaction degree should be detected is determined according to the requirements of a roadbed construction site, a plurality of groups of non-settlement measurement reference points and a plurality of groups of settlement observation points are arranged, and settlement data of the settlement observation points are recorded; and S3, indoor measurement data are analyzed, specifically, settlement volumes of the different settlement observation points obtained by field measurement are fit to obtain the compaction degree of the points. According to the method, a prediction model is established by analyzing indoor numerical simulation and outdoor measurement data results, only a small amount of settlement observation needs to be carried out on site, outdoor work is reduced, compaction degree fitting can be automatically completed through a program, the detection result is reliable, and the efficiency is high.
本发明公开了一种获取压实作用下路基土压实度的方法，包括如下步骤：步骤S1：进行室内实验与数值模拟：首先路基土取样，检测压实度特性与弹性模量，建立起路基土压实度与弹性模量的关系；步骤S2：进行室外待压实道路的测量：根据路基施工现场的需要，确定应当检测压实度的区域，布置多组无沉降的测量基准点和多组沉降观测点，记录沉降观测点的沉降数据；步骤S3：进行室内测量数据的分析：对于现场测量得到的不同沉降观测点的沉降量，拟合得到这些点的压实度。本发明通过对室内数值模拟与室外测量数据结果进行分析，建立了预测模型，现场只需进行少量的沉降观测即可，减少了户外工作，压实度的拟合可通过程序自动完成，检测结果可靠、效率高。
