【正文】 ao Yun, chairwoman of British Chamber of Commerce Southwest China, told China Daily that his colleagues found the policy very convenient. A British client once flew here and stayed for just one day to check her ordered goods, she said. Zhao was born in Shanxi province, but she has lived in Chengdu for more than 10 years. My life was like a running race moving from place to place. I also lived in Beijing and Shanghai before, she said. But Chengdu is a place that you never want to leave once settling down. It is now my second hometown, she said. If the environment is further improved, the city will attract more people to visit and live, with the 72hour visafree policy and pelling conditions in transportation, culture, climate and cuisine, he said. Foreigners also gave positive feedback on the policy. A spokesman from Dell Inc said the pany has a global hub of operation in Chengdu, so the threeday visa has an immediate and positive influence on the pany39。s level of internationalization. The policy will also bring direct economic revenue, Li said. Chengdu has many cultural legacies and is also a paradise for panda lovers with the world39。 Visafree policy brings Chengdu biz, tourism boost. Making national headlines several times, Chengdu39。 ③地震液化效應 在飽和粉砂土中傳播的地震波，使得土中孔隙水壓力不斷升高，有效應力減少，當孔隙水壓力超過土層的有效上覆壓力時，形成砂土液化，導致地基強度降低。 ①地震力效應 地震可使建筑物受到一種慣性力的作用，當建筑物無法抵擋這種力的作用時，建筑物將會發(fā)生變形、開裂、倒塌。 四、論述題 在地震作用影響下地面出現(xiàn)的各種震害和破壞稱為地震效應。 擦痕常表現(xiàn)為一組彼引平行而且比較均勻細密的相間排列的脊和槽，有時可見擦痕一端粗而深，另一端細而淺，則由粗的一端向細的一端的指向即為對盤運動方向。、 深部循環(huán)帶：該帶地下水的運動不受附近水系的控制，由地質構造決定。 水平循環(huán)帶 ：位于最低潛水位以下，受主要排水河道控制的飽水層。 季節(jié)變化帶：位于最高和最低潛水位之間的地帶。 巖溶水的循環(huán)動態(tài)大致分為以下四個帶： 垂直循環(huán)帶：位于地表以下、潛水面之上。斷層面兩側發(fā)生相對位移的巖塊，稱為斷盤。 斷層面指兩側巖塊發(fā)生相對位移的斷裂面。 節(jié)理的特征是產狀穩(wěn)定，在平面和剖面上延續(xù)均較長；節(jié)理面光滑，常具擦痕、鏡面等現(xiàn)象，節(jié)理兩壁之間緊密閉合；發(fā)育于碎 屑巖中的剪節(jié)理，常切割較大的碎屑顆?；虻[石；一般發(fā)育較密，且常有等間距分布的特點；常成對出現(xiàn)，呈兩組共軛剪節(jié)理。若有支撐或襯砌，作用在支撐或襯砌上的壓力，便是拱圈以內塌落的砂體重量，而拱圈以外的砂體已維持自身平衡。塌落邊界輪廓呈拱形。土的崩解性也受土的粒度成分、礦物成分、水溶液的 pH 值、電解質濃度和極化程度的影響。 工程地質作業(yè) 4 參考答案 一、選擇題 1A 2B 3B 4A 5B 6C 7A 8C 9C 10C 二、判斷題 1 W 2 W 3R 4W 5R 6 W 7
