(急!20分)想知香港哪裡有Cantilever的結構, 橋, 任何建築物也可。

你好,請問香港在哪裡會有Cantilever的建築結構?
例如是cantilever bridge、cantilever building等。

另外,請問青馬大橋又會是cantilever bridge嗎?
如是,請問哪部分是有cantilevered、結構和受力受拉等甚樣??
如不是,香港哪條橋是cantilever bridge?

麻煩各位提供資料,並請詳細提供地點該部分功能和哪裡是cantilevered等。
非常感謝

✔ 最佳答案
我上補充上面位人兄係cantilevered bridge個答案:係近呢十幾或二十年,用balanced cantilever方法起嘅 segmental bridge,係兩個cantilever tip去到midspan會將佢地stitch埋一齊,變成一個continuous structure。不過,早年就無做stitching,反而係midspan 或者係 cantilever tips做一個hinge joint。((好似))舊個一條青衣南橋就係用呢一種design,有一個joint係中間。而因為creep呢個問題,midspan有好大 vertical deflection,不過我估Highways Department一早搞番好。

而係building方面,基本上有得十層以上,又slender的話,當佢地受到wind load,呢一d building 嘅都係cantilever。

Tsing Ma bridge is a suspension bridge, not cantilever.

Bridges may be constructed by balanced cantilever method, i.e. they are under cantilever state during construction, but would eventually stitched between 2 cantilever tips to form a continuous structure.

e.g. Tsing Yi bridge, Abedren bridge, etc.
