大学青年教师周转公寓基坑支护设计+CAD图纸
毕业论文关键词：基坑支护；钻孔灌注桩；锚杆AbstractGraduation design based on projects across the slope, rank area north of the east islocated in the top spot, site leveling elevation of 19.40 m; Site on the west side and southside is located in the slope toe, elevation and pit bottom close, without supportingmeasures. This graduation design is aimed at the north, east and southeast corner positionof supporting design. Foundation pit bottom elevation of 12.90 m, digging deepfoundation pit is 6.50 m, supporting circumference of about 120 m. According to thedesign plan descriptions of the graduation requirements, mainly in the following work:(1) Introduced the commonly used form of foundation pit supporting, summarize itscharacteristics and application scope;(2) Combining with the characteristics of the foundation pit engineering,Determinethe AB and CD segment cantilever bored piles supporting,BC segment with bored piles +a pre-stressed bolt support;(3) In view of the forms of supporting structure design calculation,And USES theprinciple is to check in deep foundation pit software 7.0 computing.(4) That involves supporting structure construction technology requirements,In viewof the foundation pit surrounding environmental protection requirements,Determine thefoundation pit monitoring requirements and monitoring alarm value.(5) Draw construction plans, including the surrounding environment maps,supporting structure plan, profile and node support structure large drawing.
