Method for determining digging depth of weakly consolidated soft rock roadbed after raining
The invention discloses a method for determining digging depth of a weakly consolidated soft rock roadbed after raining. The method is characterized by comprising the following steps: firstly, testing the optimum water content of weakly consolidated soft rock filler; secondly, paving liquid limit clays on the surface of the weakly consolidated soft rock roadbed before raining and compacting the clays to form a water seal layer, and testing the thickness of the water seal layer; then establishing a relationship model of four influence factors of the water content of the weakly consolidated soft rock roadbed, the thickness of the water seal layer, the depth of the roadbed, the rate of decay and the airing time after raining; and then backstepping and evaluating to determine the depth of the roadbed of the weakly consolidated soft rock roadbed with the optimum water content according to a water content multi-influence factor relationship model established, and further carrying out construction in the next stage after digging the roadbed. The method disclosed by the invention can be used for effectively reducing the infiltration capacity of rain and accurately determining the digging depth of the weakly consolidated soft rock roadbed after raining, so that the work amount is reduced and the construction time is shortened, and the building quality of the weakly consolidated soft rock roadbed can be effectively guaranteed.
