Embodiment 1

[0036] This embodiment provides a structural engineering-led geotechnical structured permanent support system, such as image 3 As shown, it includes support structure, main structure, partition wall 7 and backfill soil 4. In order to combine the support structure and the main structure with repeated or similar components, the basement exterior wall 3 is replaced by a partition wall 7, and the partition wall 7 only blocks Backfill the soil to bear the earth pressure. The exterior wall of the basement is canceled to form a permanent support system that only supports the earth pressure in the horizontal direction with the support structure.

[0037] As shown in Figure 2(a) and Figure 2(b), the horizontal force received by the structural system of the prior art during construction and use is actually the earth pressure exerted by the natural soil 1 on it, and in the support structure, the support pile 2 (ground connecting wall 5) bears the earth pressure in the horizontal direct...

Embodiment 2

[0045] This embodiment provides a design method of a structural engineering-led geotechnical structured permanent support system, taking the support structure as a ground connection wall as an example, such as Figure 5 shown, including:

[0046] (1) Design the ground connection wall in advance according to the sub-item factor of the permanent load, design the main structure not including the basement exterior wall, and design the connecting components:

[0047] Considering the complexity of geotechnical engineering and the existing design method (permanent support design method), choose the scheme dominated by structural engineering and coordinated by geotechnical engineering. Geotechnical engineering changes the load sub-item factor, and structural engineering cancels the basement outer wall and designs connecting members to achieve active connection. In this division of labor, structural engineering does more work than geotechnical engineering, and the changes made are grea...

Abstract

The invention discloses a rock-soil structured permanent support system dominated by structural engineering and a design method, and belongs to the technical field of underground structures. The technical solution is that the system comprises a support structure designed based on a permanent load subentry coefficient, the support structure is connected to a frame column of a main body structure through a plurality of connecting components arranged at intervals, partition walls used for blocking soil body are arranged between the adjacent frame columns, and a permanent supporting system which only bears the soil pressure in the horizontal direction through a supporting structure is formed. According to the rock-soil structured permanent support system, during design, the combined action generated after the main body structure and the supporting structure are connected is considered, so that the use of materials is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of underground structures, in particular to a structural engineering-led rock-soil structured permanent support system and a design method. Background technique [0002] At present, foundation pit support design belongs to geotechnical engineering, and underground structure design belongs to structural engineering design. The foundation pit support structure aims to serve the construction of underground structures and provide a safe and stable space for the construction of underground structures. Therefore, the foundation pit support structure and the main underground structure are an inseparable whole on the same site. At this stage, due to the separation of the two professions, the foundation pit support structure appears as a temporary measure, which wastes a lot of materials and causes environmental pollution. [0003] The existing underground structure system has the following problems: [0004] (1) ...
