Embodiment Construction

[0051] The implementation of the present invention will be described in detail below with reference to the accompanying drawings, but they do not constitute a limitation of the present invention, but are merely examples. At the same time, the advantages of the present invention are made clearer and easier to understand by the description.

[0052] Referring to the accompanying drawings, it can be known that the deep liquefaction shallow treatment method applied to the liquefiable sandy soil foundation comprises the following steps:

[0053] Step 1: Theoretical analysis;

[0054] Step 2: Determine the critical treatment depth of sand foundation liquefaction treatment;

[0055] Step 3: Determine the actual treatment depth of sand foundation liquefaction treatment;

[0056] Step 4: Determine the critical value of the processing width outside the foundation;

[0057] Step 5: Determine the actual processing width outside the foundation;

[0058] Step 6: Determine the sand lique...

Abstract

The invention discloses a shallowing treatment method for a liquefiable sand foundation. The shallowing treatment method includes the steps of theoretical analysis; determination of critical treatment depth in liquification of the sand foundation; determination of actual treatment depth in liquification of the sand foundation; determination of critical treatment width of the outside of the sand foundation; determination of actual treatment width of the outside of the sand foundation; determination of sand liquification zone according to the actual treatment depth and the actual treatment width. The shallowing treatment method has the advantages of reducing cost for treatment of the sand foundation, reducing construction difficulty and shortening construction period greatly.

Description

technical field [0001] The invention relates to the technical fields of water conservancy and hydropower engineering and geotechnical engineering, and more particularly relates to a deep liquefaction shallow treatment method applied to liquefiable sandy soil foundation. Background technique [0002] With the sustained and rapid development of my country's economy, the scale of infrastructure construction in my country's coastal areas has been unprecedented in recent years. A large number of land reclamation projects have been carried out in Yantian and other areas. [0003] Most of these projects are hydraulically reclaiming waste silt, silty sand, silt and other materials on the silted tidal flats, and then carrying out foundation reinforcement treatment; due to the unprecedented scale of land reclamation projects in my country, resulting in reclamation resources In particular, the medium-coarse sand with better seismic liquefaction has faced the situation of no sand availab...
