中國首臺自主研發的世界最大類矩形全斷面盾構機——“陽明號”已在寧波軌道交通4號線翠柏裏站始發，貫通後兩個區間約1.6千米的隧道將成為我國第一條穿越核心城區的類矩形盾構法隧道，有效破解中心城區地下空間“放不下”、兩側居民房屋“碰不得”的兩大難題。

The first self-develop near-rectangle full face shield machine of China- Yangming which is the largest in the world has started from Cuibaili station of Ningbo rail transit line 4. After connected, 2 tunnels which are about 1.6km will be the first near-rectangle shield method tunnel across core district. It effectively solves 2 problems, underground space of core district is small and houses on both sides of street can’t be moved.

　　“陽明號”盾構機由上海隧道工程有限公司（以下簡稱“STEC”）研發，2016年12月28日通過了由多位院士和業內權威專家組成的專家組的項目驗收。該裝備創新採用類矩形設計，是我國隧道工程裝備領域的重大突破，目前全球僅STEC一家公司掌握這一技術。

“Yangmin” shield machine was researched and developed by Shanghai Tunnel Engineering Co., Ltd. (hereinafter referred to as STEC ) and was checked and accepted by expert group consisting of many academicians and professionals. The machine creatively uses design of near-rectangle. It is a major breakthrough in tunnel engineering equipments field. At present, only STEC masters the technology in the world.

　　“陽明號”盾構機重達720噸、總長約59米，作業形成的類矩形隧道斷面寬11.83米、高7.27米，由STEC聯合寧波軌道交通集團有限公司、上海市隧道工程軌道交通設計研究院、同濟大學、上海交通大學等單位歷時3年聯合設計研發。該裝備打破了傳統圓形設計思路，採用類矩形設計，解決了兩台單圓盾構機同時作業造成的地下空間浪費、容易入侵周邊建築基礎，一台雙圓盾構機作業容易導致沉降控制能力不足的問題，避免了大量拆遷，節約了27%-36%的地下空間資源，強化了盾構機在軟弱地層條件下的土壓平衡能力。研製過程中，攻克了類矩形盾構機全斷面切削、異形複雜管片拼裝兩個全球性技術難題，在異型多刀盤切削系統、管片拼裝系統、推進系統等方面實現了首創性突破。

“Yangmin” shield machine weights 720 tons and length is 59m. Near-rectangle tunneling section during operation is 11.83m wide and 7.27m high. It was jointly designed, researched and developed by STEC, Ningbo Rail Transit Group, STEDI, Tongji University, Shanghai Jiao Tong University and other units. The equipment bucks traditional design thought of circular and uses the design of near-rectangle which solves problems like 2 Single-round shield machines will lead to waste of underground space and inbreak surrounding building foundations, one Double-O-Tube will lead to settling control capability shortage. It saves 27%-36% underground space and strengths shield machine’s EPB capacity under the circumstance of soft soil. During development process, it solved two global technical problems, near-rectangle shield machine full section profiling and Heterogeneous complicated pipe fitting. And it achieved initiative breakthrough in different multi-tool disc profiling system, segment assembling system, propulsion system and others.

　　目前該裝備已成功應用於長約420米的寧波軌道交通3號線，有效解決了流塑狀淤泥地層、穿越拔樁區、400米小曲率半徑、淺覆土穿河、轉角控制等諸多施工難題，已完工的類矩形隧道品質優良，防水效果出色，節省了約30%地下空間，施工週期縮短了30%-40%。“陽明號”類矩形盾構機的研製成功，有力支撐了城市交通地下通道、地下共同溝、地下排洪系統、軌道交通等工程建設。

Now the equipment has successfully used to Ningbo rail transit line 3 and effectively solved many construction difficulties like soft-flowing mucky ground, across pile pulling area, small Radius of curvature of 400m, shallow covering cross river,  slew control. Finished near-rectangle tunnel has good quality, and has good water effect. It saves 30% underground space and shortening 30%-40% construction period. The successful development of “Yangming” near-rectangle shield machine powerfully support urban traffic tunnel, utility tunnel, underground seepage system, rail transit and other engineering constructions.
