The Leaning Tower of Pisa was stabilized with a massive engineering operation that took place in the 90s, in the attempt to stop the monument from falling. In fact, by the end of the 80s, the Tower was slowly heading toward its catastrophic collapse.

The Leaning Tower of Pisa (Italian: torre pendente di Pisa [ˈtorre penˈdɛnte di ˈpiːza,-ˈpiːsa] [1]), or simply the Tower of Pisa (torre di Pisa), is the campanile, or freestanding bell tower, of Pisa Cathedral. It is known for its nearly four-degree lean, the result of an unstable foundation.

2003年10月1日 · In 1990 the Italian Government appointed an International Committee for the safeguard and stabilisation of the Tower. It was conceived as a multidisciplinary body, whose members were experts in arts, restoration and materials, structural engineers and …

2023年2月27日 · In 2008, engineers completed a decade-long effort to stabilize the Leaning Tower of Pisa. The stabilization involved drilling over 50 holes into the ground around the base of the tower and injecting them full of grout. This grout fills up any voids in the soil and effectively bonds the soil to the stone foundation of the tower.

2003年10月1日 · The 56-m high "leaning tower" of Pisa was constructed in three phases between 1173 and 1370 on the alluvial sediments of the River Arno, central west Italy.

2002年1月1日 · The stabilization of the Tower of Pisa has proved to be an immensely difficult challenge to civil engineers and architectural conservationists. The Tower is...

2014年1月16日 · Stabilization of the Tower was achieved by means of an innovative method of soil extraction, which induced a small reduction in inclination not visible to the casual onlooker. This technique has provided an ‘ultra soft’ method of increasing the stability of the Tower, which at the same time is completely consistent with the requirements of ...

The 56-m high "leaning tower" of Pisa was constructed in three phases between 1173 and 1370 on the alluvial sediments of the River Arno, central west Italy. Although the tower deviated from the vertical at an early stage, the continuing tilt has led to concern about its safety.

2024年8月14日 · It is well known that the foundations of the Leaning Tower of Pisa were stabilised using the method of underexcavation to reduce the southward inclination of the Tower by about 10 percent in combination with controlling the seasonally fluctuating water table beneath the …
