【正文】 Total revenue from tourism surpassed 133 billion yuan ($). During his visit to Kazakhstan in September, Chinese President Xi Jinping proposed that China and Central Asia join hands to build a Silk Road economic belt to boost cooperation. The idea has been widely echoed in Central Asian countries, being an encouraging blueprint for Chinese areas along the Silk Road that has linked Asia and Europe for more than 2,000 years. In the next three weeks, China Daily reporters will travel through the belt in China and in Kazakhstan, Uzbekistan and Turkey. They will show the progress and expectations of the countries, businesses and peoples on the route. Shaanxi the start of the ancient Silk Road has positioned itself as the new starting point for the development of the Silk Road Economic Belt, which will strengthen China39。s ancient indigenous religion, while Du jiang yan is considered to be the oldest functioning watercontrol project in the world. Chengdu ranked third in tourist facilities, management and services among 60 Chinese cities in a customer satisfaction survey released last year. But, Li added that efforts are still needed to develop more tourism products, improve English services and provide accurate translation of traffic signs and scenic billboards. Zhao 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。 五、論述題 開挖施工過程中，軟弱地基的處理方法。 5 構(gòu)件安裝前的準(zhǔn)備工作有哪些？ 答： 1）預(yù)檢與配套； 2）柱基檢查； 3）標(biāo)高設(shè)置及柱底灌漿； 4）構(gòu)件堆放；5）機(jī)械選擇； 6）流水段劃分。（ 2）質(zhì)量檢查的內(nèi)容： 1）接頭部位是否符合要求； 2）外觀檢查 4 鋼筋套筒擠壓連接技術(shù)的優(yōu)點(diǎn)及適用范圍是什么？ 答： 1）優(yōu)點(diǎn)：省電、省材；易控制、便檢查；適用廣、效率高；常年施工。 答： 1）構(gòu)件的組裝順序?yàn)椋喊驳鬃?—— 安立桿 —— 安橫桿 —— 安斜桿 —— 鎖緊 —— 放腳手板 —— 安立桿 —— 安連接鎖 —— 安橫桿。 2）不同規(guī)格的鋼管 嚴(yán)禁混合使用、扣件與鋼管外徑相同。 特點(diǎn)： 吊臂長，幅度大；吊鉤高度大；起重能力大；速度快 4 起重機(jī)運(yùn)輸體系選擇的影響因素有哪些？ 答：影響因素有：建筑物的 體型和平面布置、工程量、工期，施工環(huán)境條件，本單位資源條件 等 4 混凝土泵的特點(diǎn)是什么？ 答：特點(diǎn)： 澆注速度 快、工效高；質(zhì)量好、精度高；減輕勞動強(qiáng)度；簡化文明施工。 應(yīng)力松弛：結(jié)構(gòu) 約束應(yīng)力將隨時間而逐漸減少 的現(xiàn)象。 3 預(yù)制樁施工中常遇到的問題是什么？如何處理？ 答： 1）打壞、偏斜；處理方法：重打； 2）樁打不下；處理方法：加重打 3）一樁打下鄰樁上升。 2 錨桿設(shè)置時應(yīng)注意哪些問題？ 答： 1）使用前要除銹及清除油脂； 2）拉桿安置于鉆孔的中心。 1挖槽施工中，單元槽段如何 劃分？ 答： 單元槽段的最小長度不得小于一個挖掘段，同時考慮相關(guān)條件。 1地下連續(xù)墻導(dǎo)墻的作用是什么？ 答 :（ 1）擋土墻。鋼板樁擋墻； [以上兩項(xiàng)為鋼板擋墻 ] 支護(hù)結(jié)構(gòu)有哪些監(jiān)測項(xiàng)目？各項(xiàng)目的監(jiān)測方法是什么？ 答 : 監(jiān)測對象 監(jiān)測項(xiàng)目 監(jiān)測方法 備注 支護(hù)結(jié)構(gòu) 擋墻 側(cè)壓力、彎曲應(yīng) 力、變形 土壓力計(jì)、孔隙水壓力計(jì)、測斜儀、應(yīng)變計(jì)、鋼筋計(jì)、水準(zhǔn)儀等 驗(yàn)證計(jì)算的荷載、內(nèi)力變形時需監(jiān)測的項(xiàng)目 支撐 （錨桿） 軸力，彎曲應(yīng)力 應(yīng)變計(jì)、鋼筋計(jì)、 傳感器 驗(yàn)證計(jì)算的內(nèi)力 圍堰 軸力，彎曲應(yīng)力 應(yīng)變計(jì)、鋼筋計(jì)、 傳感器 立柱 沉降、抬起 水準(zhǔn)儀 觀測坑底隆起 的項(xiàng)目之一 工程中常用的擋墻結(jié)構(gòu)有哪些形式？ 答 : （ 1）鋼板樁擋墻；（ 2）鋼筋混凝土板樁擋墻；（ 3）鉆孔灌注樁擋墻；（ 4） H 型鋼支柱；（ 5）地下連續(xù)墻；（ 6）深層攪拌水泥土樁擋墻；（ 7）旋噴樁帷幕墻；（ 8） 環(huán)梁支護(hù)。 （ ） 3 普通螺栓靠連接板間的摩擦阻力來傳遞剪力。 （ ） 3 搭設(shè)鋼管扣件腳手架的立桿時，不同規(guī)格的鋼管可以混合使用。 （ ） 2 混凝土結(jié)構(gòu)載荷載作用下，如保持約束變形為常量，則結(jié)構(gòu)約束應(yīng)力將隨時間逐漸減少，此現(xiàn)象稱為應(yīng)力松弛。 （ ） 1土層錨桿施工包括鉆孔、泥漿護(hù)壁、安放拉桿、灌漿和張拉錨固等過程。 （√） 地下連續(xù)墻施工振動小、噪聲低，非常適合在城市中施工。 4 碳素結(jié)構(gòu)鋼的 Q235C表示（ C、屈服強(qiáng)度為 235N/m ㎡， C級鎮(zhèn)靜鋼 ）。 2 在樁基礎(chǔ)施工中，（ A、預(yù)制樁 ）的質(zhì)量控制原則是以控制貫入度為主，
