Each building adopts a frame shear wall structure, and steel truss corridors are set up on the second floor between floors B and E, as well as between floors D and E.

1、地基与基础

持力层为细砂③层、粉砂③1层，地基承载力标准值130kPa，主楼上部荷载较大，特别是持力层中度液化。综合对比天然地基、桩基础、地基处理等地基形式后，结合经济适用等目标，进行了地基承载力修正分析及沉降分析，经专家会论证，最终选择天然地基+平板式筏基的方案，相对其他方案节约了建筑材料，节省了工期，带来了巨大经济效益。

E楼大空间区域存在抗浮问题，综合比较了抗拔桩、压重、抗浮锚杆三种抗浮方案，因压重方案需要增加较大的基坑深度，抗浮锚杆带来防水难以处理的问题，最终采用抗拔桩解决抗浮问题。

1. Foundation and foundation

The bearing layer consists of layer ③ of fine sand and layer ③ of silt. The standard value of the foundation bearing capacity is 130kPa. The upper part of the main building has a large load, especially the bearing layer is moderately liquefied. After comprehensive comparison of natural foundation, pile foundation, foundation treatment and other foundation forms, combined with economic and applicable objectives, the foundation bearing capacity correction analysis and settlement analysis were carried out. After the expert meeting demonstrated, the natural foundation+flat raft foundation scheme was finally selected, which saved building materials, saved construction period and brought huge economic benefits compared with other schemes.

There is an anti floating problem in the large space area of Building E, and three anti floating schemes, namely anti pulling pile, pressure weight, and anti floating anchor rod, were comprehensively compared. Due to the need to increase the depth of the foundation pit for the pressure weight scheme, the anti floating anchor rod caused a problem of difficulty in dealing with waterproofing. Finally, anti pulling pile was used to solve the anti floating problem.

2、结构抗震设计

本项目抗震设防烈度为8度，设计地震分组为第二组，为标准设防类。为满足建筑功能需要，部分剪力墙在B1顶板框支转换，为加强结构性能，满足抗震计算要求，部分柱及核心筒内设置了钢骨。

The seismic fortification intensity of this project is 8 degrees, and the design earthquake group is the second group, which is a standard fortification category. To meet the functional needs of the building, some shear walls are converted to B1 top plate frame support. To enhance structural performance and meet seismic calculation requirements, steel ribs are installed in some columns and core tubes.

3、预应力结构设计

B楼、D楼部分大跨度结构，采用了预应力梁和预应力空心楼盖的结构形式，降低结构高度，满足建筑净空要求。预应力空心楼盖还能降低结构自重，增强楼层间隔音效果。

3. Design of prestressed structures

The large-span structures of Building B and Building D adopt the structural form of prestressed beams and prestressed hollow floors, reducing the structural height and meeting the building clearance requirements. The prestressed hollow floor can also reduce the structural weight and enhance the sound insulation effect between floors.

4、 E楼及连廊大跨度结构设计

E楼大跨度屋盖采用钢桁架结构，各楼间钢连廊采用一端滑动、一端铰接的钢梁或钢桁架，采用成品钢支座，钢支座满足滑动或转动的要求。

4. Design of Large Span Structure for E-Building and Corridor

The large-span roof of Building E adopts a steel truss structure, and the steel corridors between each building use steel beams or trusses with one end sliding and one end hinged, using finished steel bearings that meet the requirements of sliding or rotation.
