Combined foundation monitoring method for dynamic compaction reinforcement
The invention provides a combined foundation monitoring method for dynamic compaction reinforcement. The combined foundation monitoring method comprises the steps that soil pressure boxes and pore water pressure gauges are arranged at the position of a roadbed center drill hole of each section, the burying depth is 1-8 m, testing probes are arranged every 1 m depth, and in the dynamic compaction process, the soil pressure boxes and the pore water pressure gauges are used for monitoring the soil pressure change condition and the hyperstatic pore water pressure change condition of a foundation soil body within different depth ranges; and inclinometer pipes and matched settlement magnetic rings are drilled and arranged on the two sides of a dynamic compaction treatment boundary respectively according to the distances of 1 m, 4 m, 7 m and 10 m away from the boundary, and the magnetic rings and the inclinometer pipes are used for monitoring in the dynamic compaction process to obtain the change conditions of the layered settlement amount and the lateral displacement amount of soil bodies at all depths of a foundation at different positions outside the dynamic compaction boundary. According to the method, dynamic compaction disturbance is reduced, and meanwhile a whole set of parameters including foundation layered settlement deformation, hyperstatic pore water pressure, soil pressure, lateral displacement and the like can be collected.
本发明提供了一种针对强夯加固的组合地基监测方法。包括：将土压力盒、孔隙水压力计布置在每个断面的路基中心钻孔位置，埋设深度1～8m，每间隔1m深度布置一个测试探头，在强夯过程中利用土压力盒、孔隙水压力计监测地基土体不同深度范围内的土压力、超静孔隙水压力变化情况；将测斜管与配套的沉降磁环分别钻孔布置在强夯处理边界的两侧，且按照距离边界1m、4m、7m和10m的距离布置，在强夯过程中利用磁环和测斜管监测可以得到距强夯边界外不同位置地基各深度土体分层沉降量和侧向位移量的变化情况。本发明在减少强夯扰动同时，可以采集到一整套包括地基分层沉降变形、超静孔隙水压力、土压力和侧向位移等各项参数。
