- Abstract:
-
In the joint support structure of pile anchor and soil nail, the distribution of earth pressure between pile anchor and soil nail is the key to the design of joint support structure. The strengthening of soil nails will significantly reduce the soil pressure directly acting on the pile anchor structure, thereby reducing the stress level of the bolt in the pile anchor structure and shortening the depth of pile insertion into the soil. Under normal circumstances, the side wall of the foundation pit of the joint support structure of pile anchor and soil nail is very small, and there is generally no significant rupture surface within the length of soil nail, and the soil nail support part can be regarded as an intermediate unit in the process of earth pressure transmission to the pile anchor structure. Based on this, the distribution of earth pressure between the two supporting structures and the coordinated deformation of the joint support structure can be calculated. Through the calculation of the side wall of the foundation pit and the comparison of the monitoring results, the engineering applicability of the earth pressure distribution mode is verified, which has certain reference value for the design and calculation of similar supporting structures.
