However, when there is a retaining wall on the grouting bank, the high-pressure grouting will generate a horizontal thrust on the retaining wall. If the grouting pressure is too high, the retaining wall on the bank will slide horizontally under the action of this thrust and be damaged.
At present, the impact of high-pressure grouting on the bank retaining wall is mostly judged based on experience, and no relevant theoretical methods have been used to predict it.

Embodiment 1
[0039] The back of the retaining wall on a certain bank is a filled soil foundation. Because a building needs to be built on the top of the filled soil, it is necessary to perform high-pressure grouting treatment on the filled soil foundation to improve the bearing capacity of the foundation. Since the retaining wall is close to the high-pressure grouting area, in order to judge whether the high-pressure grouting will cause sliding damage to the retaining wall, the method of the present invention is used to predict it.
[0040] First, according to the construction plan of high pressure grouting treatment, the diameter d of the high pressure grouting hole is determined 0 is 0.20m, the grouting pressure p 0 is 1200kPa, and the longitudinal spacing W of the grouting holes is 1.0m; the distance L between the retaining wall and the nearest row of grouting holes is determined according to the on-site measurement and construction plan 1 is 6.2m, the lateral spacing L of each row of ...

A method for predicting the anti-sliding stability of high-pressure grouting to a shoreside retaining wall comprises the following steps: firstly, determining the diameter d0 of high-pressure grouting holes, the grouting pressure p0, the longitudinal distance W of the grouting holes and other on-site actual parameters, then calculating and determining the parameters of a soil body behind the retaining wall through the parameters, and finally, comparing the parameters to judge the anti-sliding stability of the retaining wall. By means of the method, the prediction method for the anti-sliding stability of high-pressure grouting to the shoreside retaining wall is simple, and the prediction result is accurate.
Description
technical field [0001] The invention relates to the field of infrastructure construction, in particular to a method capable of predicting the anti-sliding stability of a bank retaining wall during high-pressure grouting. Background technique [0002] Soft soil foundation high-pressure grouting treatment is a common foundation treatment method. By injecting cement slurry into the soft soil foundation, a composite foundation is formed to jointly bear the upper load. However, when there is a retaining wall on the grouting bank, the high-pressure grouting will generate a horizontal thrust on the retaining wall. If the grouting pressure is too high, the retaining wall on the bank will slide horizontally under the action of this thrust and be damaged. . At present, the impact of high-pressure grouting on the bank retaining wall is mostly judged based on experience, and no relevant theoretical methods have been used to predict it. Contents of the invention [0003] The purpose ...
