问题:

某建筑物设计使用年限为50年,地基基础设计等级为乙级,柱下桩基础采用九根泥浆护壁钻孔灌注桩,桩直径d=600mm,为提高桩的承载力及减少沉降,灌注桩采用桩端后注浆工艺,且施工满足《建筑桩基技术规范》JGJ94-2008的相关规定。框架柱截面尺寸为1100mm×1100mm,承台及其以上土的加权平均重度γ0=20kN/m3。承台平面尺寸、桩位布置、地基土层分布及岩土参数等如图20-24(Z)所示。桩基的环境类别为二a,建筑所在地对桩基混凝土耐久性无可靠工程经验。

假定,在桩基沉降计算时,已求得沉降计算深度范围内土体压缩模量的当量值=18MPa。试问,根据《建筑桩基技术规范》JGJ94-2008的规定,桩基沉降经验系数φ与下列何项数值最为接近()。

A.0.48

B.0.53

C.0.75

Locks

You have a special card which operates the electronic lock on your room door and a key for the main door of the door of the hotel. These are your responsibility and should never be lent to anyone, including your fellow classmates. If you lose them you will be charged £20 per replacement. Do not leave your room unlocked even for short periods. Unfortunately, theft from student hotels is very common and insurance companies will not pay for stolen goods unless you can prove that your room was broken into by force.

☆Visitors

There are rarely any rooms available for visitors, except at the end of the summer term. Stan Jenkins, the hotel manager, will be able to tell you and can handle the booking. A small charge is made. Stan also keeps a list of local guesthouses, with some information about what they’re like, price, etc. You are also allowed to use empty beds for up to three nights, with the owner’s permission (for example, if the person who shares your room is away for the weekend ), but you must inform Stan before your guest arrives, so that he has an exact record of who’s in the building of a fire breaks out. Students are not allowed to charge each other for this.

☆Kitchens

There is a kitchen on each floor where light meals, drinks, etc. maybe prepared. Each has a large fridge and a food cupboard. All food should be stored, clearly marked with the owner’s name, in one of these two places. Bedrooms are too warm for food to be stored, and the cleaners have instructions to remove any food found in them. After using the kitchen, please be sure you do all your washing up immediately and leave it tidy. If you use it late in the evening, please also take care that you do so quietly in order to avoid disturbing people in nearby bedrooms.
