Embodiment Construction
[0021] The present invention will be further described below by embodiment:
[0022] Concrete design procedure of the present invention is as follows:
[0023] (1) According to the upper load conditions, calculate the additional pressure 3 of the base.
[0024] (2) Calculate the influence depth of the additional compressive stress 3 according to the diffusion theory and foundation code.
[0025] (3) Calculate the corresponding additional compressive stress intensity within the depth range affected by the additional compressive stress.
[0026] (4) Calculate the corresponding lateral expansion force 4 according to the intensity change of the additional compressive stress, and determine the required constraint depth according to the intensity of the constraint force. The direction of passive earth pressure 5 is opposite to that of lateral expansion force 4 , and the magnitude is the same, which is the reaction force of lateral expansion force 4 .
[0027] (5) Set the restrain...
