    GeoChina International Conference will organize a technical tour to visit the Qiantang River.The Qiantang was historically known as the Zhe River or Zhejiang, which gives the name to the province.

    The Qiantang River (Chinese: 钱塘江) or Qian River is an East Chinese river that originates in the border region of Anhui and Jiangxi provinces. Its upper stretch is called the Xin'an River, and the middle stretch the Fuchun River (富春). An important commercial artery, it runs for 459 kilometers (285 mi) through Zhejiang, passing through the provincial capital Hangzhou before flowing into the East China Sea via Hangzhou Bay. The river was the southern terminus of the ancient Grand Canal that links five major rivers in China from north to south, and enables water-borne traffic to travel inland from Hangzhou as far north as Beijing.

    The river and the Hangzhou Bay are known for the world's largest tidal bore. The oldest known tide table (AD 1056) is for the Qiantang River and may have aided ancient tourists wishing to see the famous tidal bore. The tide rushing into the river mouth from the bay causes a bore which can reach up to 9 metres (30 ft) in height, and travel at up to 40 km per hour (25 miles an hour). Known locally as the Silver (or Black) Dragon, the wave sweeps past Hangzhou, menacing shipping in the harbor.

    The bridges and tunnels crossing the Qiantang River link the main urban area with Xiaoshan area of Hangzhou. For a long time, they have been important transport hub of Yangtze River Delta region. Until now, there have been ten bridges since the construction of the first bridge in 1934. These bridges include highway bridges, railway bridges as well as combined highway and railway bridges. The bridges are steel truss bridges, continuous girder bridges, cable-stayed bridges, arch bridge and suspension bridges. Among all these bridges, the Third Qiantang River Bridge was selected as an exclusive passageway in Hangzhou for the 2016 G20 summit.

    The technical tour consists of visiting of three major projects:
        (1) the third Qiantang River Bridge (Xixing Bridge)

        (2) the fourth Qiantang River Bridge (Fuxing Bridge)

        (3) the eighth Qiantang River Bridge (Jiubao Bridge)

    (Departure from hotel lobby at 10 a.m. and end of the tour at around 6 p.m.)

    The main bridge of the third Qiantang River Bridge (Xixing Bridge), is a pre-stressed concrete cable stayed bridge with a single central cable plane and double single pylons. The total length of the bridge is 1280 m with the main span of 168 m. The bridge used fixed pier-pylon-beam system and harped cable plane. The main bridge of the fourth Qiantang River Fourth Bridge (Fuxing Bridge), is a double-deck concrete filled steel tube composite tied-arch bridge with two main arches. It is made up of two parts with the length of 85 m and 190 m. The shorter part is a combination of through tied-arch bridge and deck type bridge, while the longer part can be divided into a through tied-arch bridge and a half-through one. One arch is separated from the other, and the connection between superstructure and substructure are the simply supports. The eighth Qiantang River Eighth Bridge (Jiubao Bridge)with the total length of 1855 m is made up of a main bridge in 3×210 m and other approach spans. It was finished in 2011. The main bridge is a composite arch bridge, and the approach bridges take the form of multi-span continuous composite box girder bridge with the uniform cross section. The construction method is the incremental launching method.
