Abstract

The invention provides a roadbed construction method of a peat soil foundation. The roadbed construction method comprises the following steps of an acquiring step, specifically, acquiring the optimalwater content value of sea sand in the maximum dry density state; a laying step, specifically, laying the sea sand on the peat soil foundation; a watering step, watering the sea sand to a preset degree; a rolling step, specifically, rolling the watered sea sand; and a detecting step, specifically, detecting whether the compaction degree of the rolled sea sand meets the preset standard or not, determining the preset standard according to the optimal water content value, and if the compaction degree of the rolled sea sand does not meet the preset standard, repeating the watering step, the rolling step and the detecting step till the compaction degree of the rolled sea sand meets the preset standard. By means of the roadbed construction method, the roadbed construction quality of the peat soil foundation can be effectively guaranteed, the construction difficulty is lowered, and the construction progress is accelerated; in addition, the sea sand is used for filling, especially in coastal areas rich in sea sand resource, resources can be effectively utilized, and the engineering cost is saved; and according to the method, static pressure is only needed once, repeated rolling is not needed, and the construction steps and the engineering cost are saved.

Description

technical field [0001] The invention relates to the technical field of roadbed construction, in particular to a roadbed construction method for a peat soil foundation. Background technique [0002] Peat soil is rich in organic matter, which is formed by the accumulation of a large number of insufficiently decomposed animal and plant residues under anoxic conditions. The lower the degree of degradation, the more residual fibers contained in the soil; the higher the degree of degradation, the more amorphous humus in the soil. The higher the content of organic matter, the greater the impact on soil quality, mainly manifested in low strength and high compressibility. When carrying out subgrade construction on peat soil foundation, due to the characteristics of peat soil, traditional subgrade treatment methods, such as using clay and mechanical rolling, increase the construction difficulty, reduce the construction quality, and slow down the construction progress .
