新填地

中環填海

新填地係指揼等入,填成。填嘅水可以指、或者。世界近海各,多數有填海。古時亦有圍,尤其喺淺灘,久而久之變成大片新填地。亦有抽乾地,雖然無新地,但將爛地變成人用得嘅地,都算係新填地嘅一種。

現今造地係土木工程一範,填地方法首先圍起要填嘅水域,跟住用大石水泥,加較碎沙石填塞。填地目的多數為咗經濟,擴展海邊地。亦有為清垃圾而填地,尤其係裝修、舊樓重建、工業廢料。工程亦要注意防漏,以免沙泥等污染水域。

新填地大多唔係即刻起得高樓大廈,因為土質有水份會有沉降,所以頭嗰十年八年新填地只可以做公園、海濱廣場等[未記出處或冇根據]

新填地怕地震,地震時,填地有可能流質,上面屋宇有危險[1]。新填地起屋,一定要反覆壓實,防止泥土化成流質。
